it will fire with starter fluid but will not run after you get it to fire? Have you checked the coil packs? I can't think of anything that you did when you added oil and coolant that would affect any of the electrical... was it running fine up to that point?

 

I removed a vacuum hose in the intake manifold and sprayed in contact cleaner. It will start and idle nicely for as long as I want to stand there and spray, so I figured the coils must be ok. It was running fine up to that point.
Although now that I think about it, about a month ago I walked by it in the driveway as it was parked and heard noise. I checked and found that one of the relays (I dont remember which) was chattering. I grabbed a key and started it up, then shut it off and haven't had a problem since.

 

Are you getting fuel through to the intake? If it is running only when you are spraying it it could be lack of fuel. You might also have gotten contaminated fuel try adding a cup full of methylated spirits to the fuel tank, this will help clear any water from fuel and lines. Hope you can solve it soon, best of luck.

 

if the injectors aren't getting pulsed the ECU might not be getting a signal from the crank or the cam sensor.

 

if the injectors aren't getting pulsed the ECU might not be getting a signal from the crank or the cam sensor.

I think these must be in order because it runs on starter fluid.

 

Thanks guys, I'll check those next and post tomorrow. In the back of my head im thinking its a sensor or something electronic thats shutting off those circuits.

 

yeah if it runs on starting fluid he has spark and good timming


your not getting fuel even if the pump works if the injectors arnt you wont get anywhere..... could you have spilt oil or coolant or anything on any of the connectors fuses or relays anywhere?

 

yeah I know it won't pulse the injectors without a signal from the cam or the crank... but it should still spark with a signal from the crank sensor. As long as the crank sensor gives a PIP signal to tell the ECU when to fire it will give spark to the plugs. The Cam signal gives a CID signal to the ECU. Without the CID cam signal the plugs should still fire, but the engine will attempt random coil syncronization so several attempts (key on, key off) to start may be required before it finds the proper sequence to start.

Without the Cam signal you WOULD still get spark, but your injectors WOULD NOT be opening.
Without a Crank signal you WOULD NOT have spark and your injectors WOULD NOT be opening.

In either case, you should have a trouble code on the ECU to indicate a bad sensor. SHOULD is the key word there. The sensors don't always throw a code, you may have one pending and no CEL.

 

Thanks for all the input. last week I jumped the fuel pump and checked pressure, ok. No injector pulse though. I then went salmon fishing for a few days, but the darn thing didn't heal while I was gone:lol: I guess I will start checking sensors next, starting with the cam sensor.
Another thought, Is there a sensor on both cams? If one cam jumped a tooth could a sensor shut me down but still show that im in time with my timing light?

 

Only one sensor on the exhaust cam.

Time they worked on self healing cars !!!

 

^^ x2 on the self healing car.

 

Even though I have no active fault codes, I rechecked all sensor connections, I cant find any values published to ohm out or otherwise check any of them. I still have a "pending" 0561 code, (system voltage unstable) I cleaned up all the grounds...again. Battery connections are primo. Everything going into the ECM appears as it should be. I am beginning to wonder if I have an ECM internal short, as I am just not getting voltage to the fuel pump or 02 sensor circuits in the fuse panel.

 

Fixed!!!

Started all over again diagnosing the P0561 fault code. unclipped and pulled out wiring harness from injectors and sensors over to relay box. Removed all split loom and started ohming out wires. Found corrosion in a white and blue wire for about 3" from C182 connector on the engine side. Cut out the corrosion and jumped that wire around the factory connector with a spade connector. checked the rest of the harness and reinstalled it all. All circuits came back to life.
She fired right up. Pretty damn time consuming but my labor is cheaper than the dealers. Thanks for all the advice gentlemen.:beer:
Adios.
