gotta 95' jdm h22a swap..i dont have a oil pressure switch and theres a Map sensor on top of my throttle body isn't that for OBD2? but all the wiring is obd1..car isn't starting i wanted to know if this is the problem

 

OBDI also has the MAP sensor on top of the throttle body. Do you have the ECU wired correctly? And what year did the H22A come out of? Using the same year engine as your car makes it much easier.

 

OBD1 map in not on the throttle body, its on near the fire wall. Just what year is the engine.

 

Your car is obd2 ver a obd1 h22a correct. Do you have the obd1 ecu and did you consider a obd2 to obd1 conversion harness?

 

i have a 90' accord..its a jdm 95 h22a that came with the obd1 p13..everythings plugged in except the IAB i just dont have a oil pressure switch, and i didn't hear about wiring up the MAP sensor on top of the jdm h22a i didn't think it was needed

 

It should still run without the MAP sensor hooked up, just really rough. The engine won't start as in....does it crank and not fire or what?

 

it cranks theres spark and it starts when i spray the quick start but it doesn't stay on..u think it could be the timing is off by a tooth or so?

 

So your saying that neither the map sensor nor the oil pressure sensors are connected.

 

dont have a oil pressure sensor and the Map on top of the TB isn't connected..didn't kno i needed it for the ODB1 p13

 

Do you have an inductive timing light, you could just check it. If the timing were off, you'd probably hear the pistons smashing into the valves. If it starts with quikstart or whatever, then I'd look at your fuel pump/filer, maybe your injectors. I swapped an engine that had been sitting a while before and the injector rail was junk, just used the injectors off the old engine and it worked fine.

 

yea the motor was sittin for a while, i used the rail from the f22a4, maybe the injectors are shitty..im gonna try that timing light tomorrow i'll borrow 1 from a friend

 

cb7tuner.com is your freind. You dont have to do any thing to the map on top of the TB. Your map is on the firewall and its still plugged in. dont worry about that.

 

oh aiight thanks man..yea im a member of cb7tuner, just get faster responds on H-T

 

wut up man my bro has an accord with a H22a and thats all he messes with. He said his pretty much did the same thing because the engine sat for a lil bit. he said just take a ratchet or something and tap on all of the injectors. If they are clogged it might knock it loose or you could just take the whole fuel rail off and clean everything out. He is also a member of cb7tuner.com and if you go there you will find out alot of info.

 

did that..used the noid tester and theres no current gettin to the injector plugs.
