Super huge thanks to importwarrior on this one. Car had been sitting almost 4 years and is back on the road again. Now to fix all the other little things that are wrong with it from sitting for so long.

This is sweet, can't wait to see more.

Still no progress here, anybody got any other ideas? or an ecu I can borrow for test purposes, lol?

Still the same symptoms. Starts when cold, runs for a bit and dies. Just seems to be getting worse. Also haven't had an entire day to go through everything yet.

So now that its a bit warmer out, I've had a little bit of time to check out the car again. Got a little 194 bulb and two wires hooked up to the primary and it appears to just turn the bulb on as opposed to pulsing. Addtionally I can't really keep the car running now. The bulb brightens and dims as the car goes up and down in rpm. Not sure what this is indicating.

Hey Thanks for all the responses, looks like I have some work to do. WIll get back to everybody after checking all these things. Quick answer, yes lots of black smoke, like it's running really rich.

Hey guys, quick question, possibly dumb noob mistake . Has anyone ever hooked up the battery cables to the incorrect terminals, or hooked up a charger to the battery with the cables switched. If so what would happen? Fry the ecu? or something else? I'm thinking I may have absentmindedly done this at one point and fried something. Would be the dumbest mistake I've made yet, but if these symptoms I'm seeing are indicative of a fried ecu/eci system then it would explain a lot. Thanks

Replaced the timing chain, still same problem.... Pretty sure I'm missing something really stupid at this point. Car has great fuel pressure, idles fine, is timed correctly, now has new timing chain and sprockets. Fresh spark plugs, wires and distributor cap are good. I'm at a loss here

Went ahead and got the timing chain set for replacement. Anybody know all the gaskets I'll need to replace the timing chain?

Fuel filters and fuel lines are also great. no clogs or anything. There is a bit of sediment in the tank but I didn't think it was enough to cause an issue.

Here's the fuel pressure when the car dies. Pic is kinda hard to see, but looks like it's around 38-39psi.

Would you be willing to part with just the 83 Hood?

Is anything still available?

Any other thoughts before I attempt to tear into the front end of my engine?

It's pretty stretched though, takes about 5degrees maybe more of crank rotation before the distributor even starts to move.

Soooo... got around to checking the timing chain, and there is a lot of play in the chain it looks like. Possibly throwing the cam timing off so far that it just doesn't want to make boost. Does make any sense? It may not be all my issues, but I don't know what else to check at this point.

This is true

So went through some other things in addition to what's listed above. I'm still not 100% on fuel pressure, dont have a gauge, but it really does look like it is getting plenty of fuel. Can hold my thumb on the line and it pushes hard. The return line is also clear. All the filters are clean and flowing well. Pulled off injectors and flowed them and checked for leaks, and they seem great as well. Checked continuity through the wires of the cts to the ecu and there is little to no resistance. Cts is brand new and ohms out properly. Timing seems perfect. Plugs are new, great spark. Set tps and checked isc. Still cannot figure out why the car gets warm and just dies, then is very difficult to restart and keep running. Not sure where else to go from here or what to check. Also spent about 3 hours last night reading through the fuel injection section of the FSM, and checking any post on the forum here that had anything to do with a non starting issue or bad idle problem. Any other ideas fellers? Thanks.

Do you happen to have part numbers for those? Would like to get a similar set up for mine as well. Would I be able to go buy a cheap fuel pressure gauge and a T fitting and throw it inline?

Yah would probably help a ton. Doesn't it require a special fitting for the fuel pressure gauge though?

Pump was just replaced, and it seems like it has pressure all the way to the injectors even when the car is warmed up. So confusing....

Does the computer get the signal to trigger the injectors from the distributor?

Have reset tps and isc, and car seems like it has great fuel pressure even after dieing.

Hey guys, have been searching through the forum quite a bit for similar issues and have replaced some parts and checked some things that similar posts have provided answers to, however am still very stumped. I'll try to be as descriptive as possible. Car is an 89 conquest, manual, has some mods, hard pipes and bigger intercooler, 2 1/2 inch exhaust piping and hks muffler. Was running about 17psi before this issue showed up. The turbo seems like it may be dying, but is not currently the issue I'm facing. Real issue at the moment is car dies after warming up. I have replaced coolant temperature sensor. Compression on all cylinders are around 110-120. Spark seems very good and timing is set. New fuel pump, filter is nice and clean as well. The car has what appears to be good fuel pressure all the way up to the injectors, but after the car warms up it sputters and eventually dies. I then pull off the ovcp and visually inspect the injectors through the throttle body and while cranking the car over (cranks very well), there seems to be no fuel coming out. Thanks for any advice in advance, great forum so far, hopefully after figuring this issue out I can contribute my findings to the information already here. it starts and runs when cold once it runs and starts to warm up it dies. as soon as the ECU temp sensor cools the process repeats. tried new ECU Temp Sensor same results.

Should I ask questions here? I've done quite a bit of searching, and am starting to feel like none of these cars have the same issues as any of the others.
