baauto Posted September 28, 2010 Report Share Posted September 28, 2010 86 starion 2.6 engine cranks but no start. There is no spark or injection pulse. Have all powers & grounds for the distrubutor & ecu. There is power to the injectors. but the ecu is not grounding the injectors. I have changed the distributor, ecu & ignighter. I can't see any other sensors that would conflict with pulse & spark. Does anyone have any ideas? Link to comment Share on other sites More sharing options...
taquito Posted September 28, 2010 Report Share Posted September 28, 2010 starter sucks and or hear me out you might have to check your cap and rotor and make sure the rotor is hitting the cap contacts this is assuming that the engine cranks over at least once or twice. Check the starter first make sure its grounded. Link to comment Share on other sites More sharing options...
taquito Posted September 28, 2010 Report Share Posted September 28, 2010 sometimes you have to pull the rotor off of the dizzy and just scrape the contact on the concrete or sand it a bit just lightly to make sure it makes good contact. Check the cap itself as well. This might actually be the solution ive seen it happen before. Link to comment Share on other sites More sharing options...

baauto Posted September 28, 2010 Author Report Share Posted September 28, 2010 remember have all powers & grounds to ecu distributor & power to injectors Link to comment Share on other sites More sharing options...
MikeMeyerhoff Posted September 29, 2010 Report Share Posted September 29, 2010 Is the fuel pump getting power? There is a electrical connector for testing the fuel pump near the air can. If the fuel pump is not getting power, there is a possibility its the main power relay. Link to comment Share on other sites More sharing options...
vbrad511 Posted September 29, 2010 Report Share Posted September 29, 2010 (edited) What ignitor have you changed? Is it the black one one the driver's inner fender labelled "knock box"? It's the ignitor on the pre 88 cars, and they're prone to failure. Rap on it a bit with the head of a screwdriver and see if that changes anything.

baauto Posted September 29, 2010 Author Report Share Posted September 29, 2010 there is fuel pressure. Yes I did change the knock module on the drivers fender well. I have no injection pulse or spark. I do have power @ injectors ecu & distributor. Grounds @ distributor & ecu. Ecu is not grounding injectors.

scott87star Posted September 29, 2010 Report Share Posted September 29, 2010 You have to forget about the injectors for now and concentrate on the lack of spark. When the ECU sees spark it will fire the injectors. Go here, look at page 29 for troubleshooting a car that cranks but does not fire. More specific tests for the ignition system start on page 165 and will give you proper resistances for the ignition pick up and coil. The distributor gives the ignitor a VR signal to indicate engine speed, the ignitor processes that controls the coil to fire at the correct timing. The coil firing tells the ECU the car is running or trying to run so it will power the fuel pump and ground the injectors. Scott Link to comment Share on other sites More sharing options...
scott87star Posted September 29, 2010 Report Share Posted September 29, 2010 My semi-educated guess is another bad ignitor, mostly since its very common and they are all very old. You can rule out the ignition pickup and coil being problems using the resistance tests, once you do that you know its a bad ignitor.
