As the description says Been trying to fix this for about a month... It cranks but it wont start, here's what I've done so far.

Start no spark changed ecm/ecu and main relay now it has spark...
Engine floods and main relay goes haywire and buzzes like crazy this happened after changing the main relay and ecm/ecu.


I did an engine swap same F22B2 engine, didn't bother changing too much but the motor mounts since basically everything else was perfectly fine.

Now I am going crazy going nearly bald trying to research what my problem is.

If you need more info I'll tell you if I missed anything.

edit: The buzzing happens when I turn the car off the the accessory after taking it off from ign1.

 

Anything? Going crazy here >:

 

guuuuuyyysss

 

Check the timing marks, be sure the firing order is correct.

If I'm reading this correct - you do have spark, the fuel injectors are working.

For grins - double check the main ground (g101). What are the color of the three wires on the map sensor?

 

Did you use a new OEM relay? A wrecker part? One that's been re-soldered?

 

Brand new relay. I re-soldered the old one but no luck, and got a new one. As for the MAP sensor wire colors I'd have to take a quick look.


Edit: The wires are two Yellow/White and one Green/White

 

If the relay is brand new, have you tried putting a different ECU in to see if the same problem happens?

You say that it started after you changed your ECU and relay, if the relay is new, maybe it's something with the ECU?

 

Ohh crap, I forgot to mention there was smoke coming from under the steering column.

 

That is a big piece of info to leave out......key to on/posII - check voltage on the BLK/YEL wire going to dist.

 

Yeah, sorry about that, i'll check on that in a bit and put it here.

 

Here's the situation today, I had checked out the black and yellow wire, it has power 12v (after charging my battery), all of the wires are also getting power, I have the fuel injectors unplugged for the sake of my engine not to get flooded with the fuel injectors are staying open and flooding the pistons... The relay still gets buzzy after taking the key from on/posII.


Any information I can answer.

 

The ground point (g101) was?

What are the color of the three wires?

 

g101 Is connected (as tight as possible)

Colors of those wires are Yellow/White, Green/White, Yellow/White

 

Problem still not solved guys. I really need help on this problem.

 

sounds like ignition switch might be bad...take it out and look at it look if burned smell if its burned

It's been a couple of months, I went through 3 ECM's Manual transmission. They have all been fried. What can cause an ECM to get fried?
