swap complete problem

[zap45]

ok started the f22b today but only one cylinder is firing. We forgot the map sensor. my question is that would a map sensor cause the engine to run off of one cylinder, also it has irregular idle too. The engine cant stay running either it just goes dead. Maybe could be the fuel injectors are bad. any suggestions? thanks.

have you done a compression test?
who did you buy your motor from?

 

[zap45]

let me explain better we forgot the map sensor but without it will it cause one cylinder to only work, irregular idle, or dont i just got some bad fuel injectors

tigerjapanese.com no i have not done a compression test

Check your comp, then spark to the other three, then fuel.

well we forgot about the map sensor would this cause the other three sensors to not fire or would it be the bad fuel injectors

 

[zap45]

well we forgot about the map sensor hooking up the map sensor would this cause the other three cylinders not fire or would it be the bad fuel injectors?

To check to see if your injectors are working, take a screwdriver, start the car, put the business end on the injector and your ear to the handle, you should be able to hear it ticking.

well the compression is excellent 160.0 165.0 160.0 160.0
next we will hookup the map sensor and check if the injectors are bad or not

 

[zap45]

well the fuel injectors were bad and all cylinders fired up we are almost done
thanks for ur suggestions guys

that is crazy..Ive never heard of 3 injectors going bad at the same time. Yes the map sensor helps control fuel and air delivery depending on manifold pressure. Most all the sensors do for that matter.

MAP = manifold air pressure

hmmm maybe this is why my car runs like crap too?? i too bought my b18b from tigerjapanese and my valve seals are shot, maybe my injectors are bad,
