need help on ecu will this work???

my car has been sitting for a year or so. I had to put a new crank pully on it becasue it came loose and chewed up the pully. After resetting the timing and checking the fire order (1-2-3-4.. front to rear is what i found online) I set it to TDC and I  got it started... It ran fine for a few mins but after it warmed up it went into a "limp" mode and wouldnt rev over 3,000rpms. I double.. triple and.. rechecked timing again, I made sure the cooling system didnt have any air in it by jacking up the front and filling it with coolent. When I jacked up the front a good amount of air came out of the system. So i think i got it all out... Now.. Since the last start up its in that "limp" mode from start up. It idles great but just wont rev up!! WHAT IS NEXT??? IM PULLING MY HAIR OUT HERE!!!

I saw some threads in regard to the car stuuering at 4,000rpm but it doesnt seem to fit my situation.

HELP PLEASE!!!! I want my notch back!!!

what happens when you rev it to that? just starts missing?

Curlytoprobyeah it acts as if it hits a govenor

David Byouve got 2 ig coils. sounds like one isnt working

CurlytoprobI'll go and try swapping them out. Would that let me know?

LeegamerYes.  If that doesn't work check your MAF.

swapped the coils and it did the same thing. Im looking for my volt meter to check the MAF. However, when I stomp down the gas the engine tries to die... This is the first time I tried stomping the gas. Could that narrow down the problem any?

CHECK inside of cap and rotor as well as the power transistors for the coils those are two overlooked items and sometimes are the culprit

do post when u find out what the problem is if not pm me and ill try and walk you through it.

Coolant temp? Ignition timing?

Me and SlickS12 had this problem the other day with his S12. Went to LA to fix it with him, it ended up being the inside of the cap and rotor that was fucked up not allowing his car to rev over 4k rpm, it would do the same govenor thing. Just check all your lines, sensors, clean everything, make sure you have spark, make sure you have fuel, and go from there.

+1 cap n rotor do as andrew2 said and ull be alright

Now it wont start period... And when I pull out a plug and look at the spark it puts out its a orange color... I dont know alot about electricty but I thought it should be almost white or blue

I havent checked the MAf yet.. How would I do it?

I dont know how to check it with a voltage meter. I dont know what im looking for with it. When I unplug it the engine acts the same as when its plugged in. Im no pro but I think this should make a difference... I will post a link with a video of what its doing.

im pretty sure if you unplug your MAF while the car is running it should shut off. if its acting the same whe nthe MAF is unplugged then you sir have a faulty MAF

I had the same prob with a 2000 sentra at my shop the other day. It was the MAF being faulty.
It had the EXACT same symptoms you are describing.

*UPDATE ON THIS POST*
This is now my car, and its fixed!! ha it turned out to be a bad connection with the fuel injectors. now my DD till i can afford a ka24 swap

This isn't a welcome thread but judging by ur post count, welcome!

ha thanks. ive been on this site for a little while though. the car was my brothers so we were using this site to try to fix it. i'll def be using it to do my engine swap!

ok i have a 84  ca20e 5 speed  and lookingto buy a 88 ca20e 5 speed guy thinks ecu is bad i was woundering if my 84 mk1 ecu would work on the 88 mk2?? i thought i read on here the mk1 had the 2 plug as the mk2 had the 3 or something like that but idk any info asap would be good as friday im getting the car.Thanks

Probably not. The harness pinouts will be different if I remember correctly. Also, there are provisions on the Mark II cars that are not on the Mark I cars.
