starting an rx7 thats been sitting, stalls
hi, i have an 88 rx7 turbo thats been sitting for 2 years. injectors spray it fires and wants to go, had it idiling for about 20 minutes after pull start, and as soon as u hit the gas it dies out like u shut the key off. some times it will fire and start, some times it wont. i know the afm was stuck but i freed it up. any advise?

Did you flush out the fuel system, replace the fuel filter, etc.?
|
A friend of mine had the same problem. I checked it out and noticed that the coils were going to ground. replace wires

done that
well, the tank was drained b/f it was parked, fuel is clean, i changed the fuel filter, yes, it was partially plugged, but no improvements. the spark is fine and the plugs look brand new. it floods out, and some times i can get about 1000 rpm b/f it dies out again.
|
Assuming it makes good compression, have the injectors cleaned and tested.
|
fuel pressure test?
|
yeah, it seems everyone is thinking fuel pressure, i will test it, but im still confused about when i pull the plugs out they are wet? i pulled the lower injectors, they are spraying fuel.
|
It's probably not fuel pressure unless the pump is bad. Test it anyway, but the FPR rarely fails.
|
try compression starting it yet?
|
compression starting? i switched fuel pumps, no result, it will rev a little then miss and die out
|
No idea what "compression starting" means. I think he may mean "push starting".
Have the injectors been flow tested yet? It's very common for a car that has sat to have a bad injector or two. The only way to get them working again is to have them professionally cleaned. |
Ive been having the same exact problem except mine was not parked. so i think that is not the issue. I'm gonna run some test on it today and let u know
|
tried
well, i hooked wires to the secondary injectors and turned the fuel pump on, they spray fine. ohms are about 8-12. the primarys spray when you crank it over. its got to be a computer control problem, some times i can get 2-3000 rpms b/f it misses, and dies out.
does anyone know when the secondary injectors are supposed to come on? |
The secondary injectors fire above 3800 RPM when the boost sensor reads about 2" of vacuum. Thus, they only come on under load.
Another cause of the car starting then immediately stalling is a bad AFM. Though I have not suggested this yet because you say you had it running for 20 minutes. What do you mean you "hooked wires to the secondaries"? Have you had the injectors cleaned and tested yet? Regardless of whether this is the cause, it needs to be done and is most likely the cause. |
fixed the problem
i replaced the Air Flow Meter. i t now has throttle responce and runs fine.
|
Sweet. Now, go get those injectors cleaned. :)
