Preludedude Posted October 23, 2014 Report Share Posted October 23, 2014 (edited) Rebuilt engine and primed oil pump through plug. That worked perfect. Now, I have fuel, spark, and timing is correct. Car will start and idle for a few seconds and then die. Trying to give it gas doesnt work and it will still die. What are my list of things I need to check. Car is 1988. I have NEW:-spark plugs-fuel pump-plug wires-ignition coil-etc I do have 3.5" MAF w/ MAFT installed (no telling what the settings are) if this has anything to do with car not idling... If someone could give me a rundown or a list of things to start checking, I would be most grateful. Thanks guys.

speedyquest Posted October 23, 2014 Report Share Posted October 23, 2014 (edited) Double and triple check your timing along with maybe a compression check. If you have fuel, spark, timing, and compression it should run even if poorly. Also if you have the ability to switch back to a stock mas at least temporarily I'd do that as well just to eliminate another issue. Allen EDIT: Another thought, check all the small basic things like firing order... Hey you never know lol.

Kenny G Posted October 23, 2014 Report Share Posted October 23, 2014 injectors most likely. after rebuild mine... it ran really bad too. I replaced them and ran great. evidently from sitting for a year they will dry up and stick oper or closed.... mine was flooding out. It could be a simple vacuum leak too.

Preludedude Posted October 23, 2014 Author Report Share Posted October 23, 2014 (edited) Has brand new 650/950 injectors and new injector clips..I replaced all this also..Well, the car has been sitting for about 4yrs also after I rebuilt engine...So all these new parts were put together and has been sitting for a while... Just got back into this car. Vacuum is possible...There are so many..Where do I check first? Any vacuum nipples were plugged that I saw open...

Preludedude Posted November 3, 2014 Author Report Share Posted November 3, 2014 (edited) Ok guys...Had a day to work on car again...Still not wanting to crank up...You guys told me to check the main 4 things here::: Spark- I have spark on all 4 plugs, and have new plugs&wires Compression- I have compression on all 4 cylinders - 1-160, 3-155, 4-150, 2-150 Fuel- I have new 650/950 Injectors and new clips...(injectors were bought from Brian @ Lower Shores 4 years ago) (these cant go bad sitting never used???)-cylinders are getting gas because it is popping and spitting pretty loud when trying to turn over, so its burning gas? Could they be flooding even thought they are new but been sitting in rebuilt engine for 4 years? How do I check to see if they are flooding? Timing- Ok, when crank is at TDC, my cam gear dowel is at 12oclock and the timing mark on cam gear was at 3oclock with the plated link lined up right...distributor cap was removed and rotor set to plug #1......Everything sound right? ---My one question, when this timing was set up as mentioned above ^, on cylinder 1, both cam lobes were pointing down, so Im assuming valves were closed on cylinder 1? Is this correct? Help me guys. Im lost here as I think I have everything set up right.... Edited November 3, 2014 by Preludedude Link to comment Share on other sites More sharing options...
Preludedude Posted November 5, 2014 Author Report Share Posted November 5, 2014 Anyone help me? I think it's flooding. When trying to crank, it's pops loud and backfires. Link to comment Share on other sites More sharing options...
markhansenconquest Posted November 5, 2014 Report Share Posted November 5, 2014 cyl 1 cam lobes should be up for valves to be closed...I think you are 180 degrees off...valves are open that's why it back fires!!!!!! can u post up pics so we can see whats going on.???? put on # 1 CYL and timing on 10 degrees Btdc..take close up pics off #1 lifters ,,So we can see if its right!!!

DSMracespeed Posted November 5, 2014 Report Share Posted November 5, 2014 I still think the distributor is off when installed on the head.Post a pic of the timing marks on the distributor with the crank at TDC,cam dowel pin at 12:00 and distributor adjustment bolt at the center of the adjustment hole.

Crap. Well this would be my problem. While on TDC on crank and dowel at 12, The lobes are down and the rocker arm is on the rounded part of cam on cyl #1. I'll take pics Friday and post. Thanks guys so much for helping me. Edited November 5, 2014 by Preludedude Link to comment Share on other sites More sharing options...
DSMracespeed Posted November 5, 2014 Report Share Posted November 5, 2014 If you're at TDC at the crank and the cam dowel is a at 12:00,then everything should be lined up properly(cam and rocker assembly is fine). Jerry L. Link to comment Share on other sites More sharing options...

DSMracespeed Posted November 6, 2014 Report Share Posted November 6, 2014 Don't care where the lobes are pointed,if dowel is at 12:00 they are where they should be....need to see where the timing marks on the distributor are with adjusment bolt in the middle.

Preludedude Posted November 7, 2014 Author Report Share Posted November 7, 2014 (edited) Ok...Here we go: Crank is at TDC: http://i1221.photobucket.com/albums/dd461/Preludedude1/FullSizeRender.jpg Cam Gear dowel is at 12oclock and timing mark at 3oclock http://i1221.photobucket.com/albums/dd461/Preludedude1/IMG_3021.jpg Cylinder 1 lobes are both pointed down: http://i1221.photobucket.com/albums/dd461/Preludedude1/IMG_3022.jpghttp://i1221.photobucket.com/albums/dd461/Preludedude1/IMG_3025.jpghttp://i1221.photobucket.com/albums/dd461/Preludedude1/IMG_3024.jpg Dizzy has rotor lined up on cylinder 1..Adjustment bolt is centered...I used a black marker on the spot where #1 spark plug is: http://i1221.photobucket.com/albums/dd461/Preludedude1/IMG_3028.jpg with everything at TDC...It looks like 1 & 2 lobes are pointed down , and 3 & 4 are mostly upwards....Is the camshaft correct? With timing set up exactly like this, the car pops and backfires when trying to start..It sounds pretty bad...

Preludedude Posted November 7, 2014 Author Report Share Posted November 7, 2014 Also just checked Injectors, the driver side (primary) sprays when trying to start the car. Doesn't look like a mist but a fan spray. Guess this is fine too. I was wondering if car was flooding. Maybe not.... Link to comment Share on other sites More sharing options...

Preludedude Posted November 9, 2014 Author Report Share Posted November 9, 2014 (edited) Been reading. Crank turns twice per cylinder one firing. I may have it on TDC but at exhaust stroke? But my cam gear dowel is at 12. So maybe not.....arghhh...I'm lost Edited November 9, 2014 by Preludedude Link to comment Share on other sites More sharing options...
markhansenconquest Posted November 9, 2014 Report Share Posted November 9, 2014 (edited) Think about this .....how can it back fire ...unless a intake valve is open???? it cant ....lifters have to fill up wih oil ....u said u just started a new engine...i think its timing.....u need to put #1 cyl on TDC and stick a straw in cyl # 1 spark plug hole and make sure u are not at bottom of stroke ..... 180 degrees off???....look at diss mark ...look at crank marks ...one tooth off on chain can mess timing all up...did u turn engine backwards ???if u did the chain can jump a tooth....more pics..

Dad Posted November 10, 2014 Report Share Posted November 10, 2014 (edited) Timing looks correct. any time crank is at TDC then 1 and 4 piston are at the top. cam determines if it's on exhaust stroke or not. both lobes down mean valves are closed. I suggest tryng stock maf to see if that changes. Edited November 10, 2014 by Dad Link to comment Share on other sites More sharing options...
