Hello,
I have a 90 eclipse 2.0 no- turbo.
The car will not start,but was driven daily until no start issue.
I have checked fusible links at battery and fuses in fuse panel.
The fuses are not blown.
I have checked ignition by replacing coil, wires ,plugs and power transistor.
Also, the fuel pressure has been checked and fpr has been changed out.
Also, the coolant temp sensor was found to be defective, but it was replaced. The TPS is bad, but not far out of range. I have checked TPS and it has a closed throttle plate value this was ok, but the resistance value when opening and closing the throttle plate is a little off, but not by much. I do not believe the TPS is causing a no-start issue for this car.
When I pull the plugs, after trying to start the car they are gas fouled. Cyl. 1 and 4 are are gas fouled worse than the other plugs. I have tried using starting fluid to start car, this does not help the car start.
I have to remove spark plugs for cleaning after a couple times of trying to start the car.When I remove spark plugs to clean them cyl.1 and 4 plugs are flooded. Cyl.2 and 3 are not very bad gas fouled. I have ohmed injectors and they are ok.
This leads me to believe it is an issue with timing.
I have checked the physical timing and all cams /crank timing marks line up.
I am thinking the Cam angle sensor may be defective. I have looked in forums for answers to this no-start issue. I need a definitive way to test CAS. Some methods to test the CAS are listed in forums. But some have indicated in forums that the CAS can not be tested. Also, the Haynes manual says the CAS can not be tested.
The CAS I have is a 4 wire sensor. One wire is 12 v power, another wire is ground, the 3rd wire is the wire for determining TDC for cyl 1 and 4 and the last wire on the CAS is for CAM inputs to the ECU
My cam angle sensor does the job of crank and cam position sensors.
This is the question I have, if Cam angle sensor is bad will I get a spark.(Autozone Manager says yes, camangle sensor can be bad and car will still have spark)
I have spark on all cyl.1-4.
I have a Haynes manual, it says the CAS for my car determines the order the fuel injectors open. Also the Haynes manual says the CAS determines TDC for cylinders 1 and 4. Could the CAS be the reason the car won't start? Is there anything else that would keep the car from not starting? Is TPS the reason for the car not starting?
Any help will be greatly appreciated?
Thanks jck
