Question about 1990 Mitsubishi Eclipse
1990 Eclipse 1.8non-turbo 82,000 orginal miles
I have fuel to the rail up to the injectors. If I pull the wire lead to the injector and hit it with a test light, I get bright light on 1 side, and a dim light on the other side. I do not know if I have a pulsing light when cranking the engine as I don't have a noid light. If I open the throtel on the plentim and spray starting fluid or dump gas in, the car fires immediately. Is it the crank sensor, cam sensor, or e.c.u.? And...how do I check these parts and in what sequence? The crank and cam sensors I can't even locate.
Thank you for any help you can give me in a solution!
Cam and crank sensors could possibly make them fire wrong but not stop them from working all together its ur ecu i have had to replace at least 20 of the with the exact same issue as long as you have good pressure to the injectors and everything is hooked up properly your gonna need an ecu sorry but good news is depending on your location they are relativly cheap

The only thing I can suggest is that you try to quiz the ECU which needs specialist equipment.
Non injection of fuel can come from several causes, and without the correct equipment, it will be a game of process of elimination.
Crank sensors are the usual ones to fail if any, and usually sit on the side of the flywheel. Look for cables going down the side of the flywheel housing. Crank sensors can be tested with a diode meter and a magnet - giving a change of output when a magnet is passed close.
Check all available keys if it has an immobiliser fitted - sometimes it's a wiped chip in the key, then check sensors, and finally ECU. I've had a blown ECU when a coilpack went faulty. Changed everything - then finally ECU solved it.
