Ok so i finally got my car to fire up, but it will only run if i work the throttle. When i let off it dies. I am getting fuel, spark and the timing is dead on. so what else could my problem be? i have tried changing the plugs out and it gets no better. I even tried my other cars distributor, iac, and throttle body. So what is my problem? You guys helped me figure out my other problem so lets get this one also. Thanks again

Any cels? and what motor? ecu? check your grounds, and all the sensors, like tps, etc etc

check your main relay.

Check your IAC and make sure you have the right plug on it. If not that, make sure your TPS and MAP connectors are not reversed.

b20vtec motor tried obd2 ecu and obd1 ecu and nothing. also grounds are good, only cel is ect. tps and map are not recersed. what else could it be

It could be your main relay. those things go bad all the time. How did you know your timing was "dead on" if your car only ran for one second?

TheYellowDart

i was refering to the timing belt being right on. as far as the dizzy timing it would start in any position i thought but would not run that great. i have tried the dizzy in many diff positions. i just swiithced the main relay out with a known good one and still nope

will it stay started if you give it gas to try to save it from dying?

your cat could be getting clogged

are your injectors dirty? what is your fuel pressure? how do the plugs look? could be running too rich.

TheYellowDart

ok i hooked up a noid light and they are all pulsing, i am getting spark, i swithced out fuel pumps and still just a 5 second run at best. one thing i noticed is i am getting a weird high pitched buzzing noise out of the iac with the key in the on position

TheYellowDart

Ok i can keep it running as long as i want but it is not running smooth. I have tried everything i can think of. Are type r injectors the same as B16? I have crower stage 3 cams, built head, b20 block with cp pistons 11.5, aebs intake mani. I have run out of ideas

my car was doing to same thing after doing my JRSC. turns out it was my map sensor controller. put my fuel enrichment relay back on which replaces that. it messes with my map sensor and iat sensor. so just give those a good check. but it was giving those same symptoms. where it would start go to idle then die

TheYellowDart

ok so i will try a new map sensor

TheYellowDart

ok so i will try map tomorrow anyone else got any ideas? after like 1 min of running the plugs are covered in blck sut, also on my exhaust mani runner number 2 was 20degrees colder than the other 3

TheYellowDart

ok i got it to idle at 1800rpm and it is deff not right sounding. So i finally could get a timing light on it and it is lined up with the white line and not the red one. so i guess my timing belt is off? If i am think correctly it would mean exhaust is off 1 tooth
