im just finishing up my h22 swap in a 92 civic, it will start run for a couple seconds then die and it wont start again, so i let it sit and go back a couple hours later and it starts then dies and i have to wait again, i know its getting spark and has fuel pressure, my grounds are all good, has anyone ever ran into a problem like this before

 

Any CELs? What ECU are you using?

 

no check engine lights on, i diid hook up the port just in case but nothing came up, im using the p13 ecm that came with the swap, also i am using f22 injectors because the h22 injectors didnot work, im not sure if that would cause any issues.

 

Well, that might be a problem. F22 injectors I think are smaller than JDM h22a injectors (345cc). The ECU is telling the injector which should be an H22 to stay open for X amount of time. If the F22 injectors are smaller, the amount of gas being delivered would not be enough. You would have to tune this lean situation out by adding fuel on the fuel maps. If you have a stock ECU, you need to stay with stock injectors.

I assume you mean something like an F22a of F22b, and not F22c (s2000 motor). Figure out what motor the injectors came from and then find their flow rates.

Are you running a resistor box for the injectors?

 

i do have a resitor box, it came with the engine, i looked it up and i have f22b injectors and the f22b and f22a injectors both run 240cc, so if i understand this right im getting fuel, just not enough to run the engine?

 

That would be my assumption. Stock JDM H22a injectors should be 345cc, USDM (obd1) H22a1 injector are ~310cc, and USDM (obd2) H22a4 injectors are either 240cc, or 280cc, I always forget that one.

Get the correct injectors installed, reset the ECU, and see what happens.

 

ok ill give it a try my h22 injectors should be under warrenty still

 

What is wrong with the H22 injectors? Just wondering. Do they not click/open for fuel to come in?

I assume the problem with the car became slightly better once the F22 injectors were installed?

 

yep they wont open at all, i though it was kinda weird that all 4 were bad, the f22 injectors work just fine though

 

Hmm.. It is odd that all 4 were dead. I have never seen that before. However, anything electrical I give the benefit of the doubt and just replace with known working parts. I hate working with electricity
