To test, no part shops will lent to you unless you know them very very well. Do you have a friend with a similar car. Best is to borrow that part from his car to test.:driver:

Hello guys!! Greetings from Greece. I carefully read all the thread , it took me about a month, (read and check) and right now ive reach a dead end! I started to have problems with my car ( del dol b16a jdm with p30 ecu non jdm virgin ). The problems starts about a year ago when the car randomly died but i could start it again. Then the problem went worse. Dificult to start and now not start at all! The classic cel on no pump prime (no cel code, just solid on). As you can see im disappointed with the situation but i don't give up! I repair the main relay , i also bought a new relay, i test the car with p28 non jdm works like a charm, then i went the ecu for tower cap replacement, still nothing , i change ic17 still nothing, and now i will receive the ecu with new qm3 hopefully working.. When its in my hands i will post a detailed pictures of the ecu. Thank you for your advice and information! You are priceless not just in the monetary way! I will keep you informed because i have a feeling that still doesn't work .. I wish im wrong. Thank you again!

Hey there E-Tech,
I've been reading thru this thread extensively. Seems like you're the man on here. Anyhow, I've been having some issues with my P28. Couple days ago, it started acting up. When I would initially turn the car on, the check engine light would go on then off as usual, but after the car runs for 5-10 seconds, then it would throw a code 3. When I swap a different ecu into my car, code 3 doesn't comes on. Have any ideas where I should start? Thanks in advance.
Cheers

Hi .. Sorry for the "lag" in reply.
Code 3 would be MAP Sensor related error.

1- all capacitors are good or changes before?
2- any "burn" marks or capacitors leaking mark?

This would help in finding the solution...

Hey E-Tech

Hey guys I'm new here but over the last 6 months of reading through this forum I have learnt alot of valuable stuff. So first off - Thanks! :)
Secondly...

I have a 96 Lancer which is a FWD chassis. I recently converted from a 1.5 to the 2nd gen (CM5A) 4g93t GSR engine.
The problem is that I need it setup for FWD. I have a Non turbo 4g93 gearbox (f5m421) which I was told would suit my setup. The gearbox bolts up fine but I cannot fit the 4g93t (pretty sure that's what it is) flywheel in the...
