hello, i am posting on this thread as i am experiencing similar symptoms to what you describe - however my car is a magna not a eclipse. does anyone know whether (or not) the problem may be transferable between these two models?
i am posting this plea for help in various relevant locations of relevant websites. i sincerely hope that i don't waste anybody's time by having them devote their valuable time to my issue more than once.
three months ago i bought a 1995 mitsubishi magna TS executive wagon (EFI). it goes absolutely fine 99% of the time.the other 1% is rendering it unreliable, as my work requires punctuality. i have so far driven the car about 5,000 kms.
1. car won't start. on turning the key, the motor cranks but it seems as if no fuel is supplied. half an hour or more later, it starts and runs as normal (very nicely, it seems).
2. motor cuts out. while cruising along, the motor suddenly cuts out (no warning noises or feelings - it is as if fuel supply is instantaneously interrupted.) car will not restart (see above). half an hour later, it starts as normal and runs perfectly.
on two occasions i have called the roadside assistance but both times, when the mechanic arrived after 45 minutes, the car then started and the mechanic was therefore unable to diagnose the problem (what problem?). similarly, i took the car to a mechanic who had a look and went as far as to replace a plug leading to the distributor cap, but again, he was unable to diagnose the problem as the car started and ran fine all day while it was in the workshop.
i have looked at some website forums for similar problems, which suggest replacing the fuel pump control relay, or a malfunction of the immobiliser but these advice are not necessarily for my model of car. is there someone out there who knows about these sort of thing and might be able to shed a bit of light on the matter? unfortunately i am not mechanically-minded enough to be tinkering around under the hood, even with the help of the manual i bought (it is an interesting but also baffling book - i'm sure i can learn a lot from it, but it doesn't make me feel confident about taking my car apart!).
cheers everybody!

QUOTE(JohnnyUtah @ Sep 17 2007, 05:03 PM) ok, I've replaced the cam sensor (after having to re-wire the damn thing so the plug would match up) replaced the fuel relay, the fuel filter, the battery, checked all my fuses, re-tested the fuel pump which (which seems to be working fine) and still nothing. It cranks and cranks and wont fire up. When I first crank it after letting it sit for a day or so, it will start right up, sputter and then die. I've spent 200 bucks on the above things that were not the problem, and now I'm afraid I'm going to have to bend over and take it to the shop...Anyone else have any suggestions before I do?? ever think that maybe it has bad gas?

I have a 93 eclipse and I've tried all the easy stuff even replacing the distributer but is still has an spark problem. Seems to fire randomly and even double some times but still doesn't start. Any ideas what to try next? QUOTE(kylewr86 @ Oct 18 2006, 11:08 PM) Too many people on the forum,say there car wont start but it cranks and tries to start. And too many people check a few things,give up, and take it to the dealer when they could save a lot of money.CHECK THE CHEAP STUFF FIRST!!!!!!!!!!!!!!!!!!!! So im gonna help out and all the moderators im sure will add things ive missed but here goes. #1 If you turn the key and nothing happens,Check the battery.This is simple just use an ohmnmeter to test the voltage.Not the battery then check the alternator and all starting circuit wires.Also check to see if the battery wires are corroded. If your car cranks over but just doesnt fire up.... First see if there is spark.Just pull a plug,And have someone try to start it. (Need help just ask) Second check to see if there's fuel at the fuel rail.There will be a test port that you can push and fuel should shoot out. If fuel does shoot out,then have someone stand by the gas tank while you turn the car on to acc.They should hear the pump prime. (DONT HEAR THE PUMP PRIME) CHECK the Fuel pump relay.Its a cheap part to buy or you can probe it.You will need a manuel though to see how and what the specs should be.Use a multimeter for that. If you bleed the fuel at the rail. turn the key to acc and also hear the fuel pump prime.. you could have a fuel pump on its way out(aka its not working all the time), clogged fuel filter,or a hose leak see if there is a puddle or some leaking underneath. BUT if fuel is at the fuel rail and you have spark,your injectors may be clogged. You can also backprobe your injectors to see if they are getting a pulse. If you work and work and nothing checks out.... THEN TAKE IT TO A MECHANIC AND SPEND THE BIG BUCKS TO SEE WHAT THE HELL IS UP. REMEMBER ALWAYS DO EASY THINGS TO HARD THINGS,too many times has the problem been a $5 fix and you gave up,took it to a mechanic and spent $500.

QUOTE(pwee05 @ Sep 18 2007, 10:40 AM) is there any kind of smoke when it actually starts? Pretty much having the same issues as everyone else (will be checking the relays today) but mine does have smoke coming out occasionally when I start it, not sure from where though...somewhere near the engine it looks like.
