22RE startup issue
I have a 1988 22RE and I'm trying to figure this out.
The first time I start it for the day, especially when cold, the check engine light will come on and it will kinda sputter like the timings off or something. If I feather the gas a little for about 5 seconds, the light goes off and it runs fine. If I turn the key to ACC first and pump the gas pedal 5-6 times and then start it, it is normal, no sputtering. After I drive it for a couple minutes I can turn it off and start with no issues whatsoever. Other than that, it drives great, MPG is normal, no other issues. Any ideas? |
Got the same problem intermittently with my 87'. However, pumping the pedal and turning to ACC shouldn't do anything on a fuel injected engine. The fuel pump doesnt turn on until the engine is actually spinning. I've always noticed that when mine is hard to start it helps to give it a little throttle too.
|
I'm hoping this isn't something serious damaging the motor when this happens. I have no idea why pumping the pedal help, but it does, or maybe its just that the pedal is pressed slightly as I start it.

Sounds a little like my 4 runner, the shop mechanics i used to work with have told me it's the EGR valve, but i have yet to hook it to a diagnostic scanner yet to verify it.
|
what codes does it throw?
|
cold start injector?
|
I just checked the resistance on the cold start injector. With neg. battery d/c'd and the meter set at 2000 I get 99 or 100 between the 2 terminals.
Can anyone tell me what that means? |
Resistance should be 2-4 Ohms.

x2 on the csi had one that would work and not changed it out and starts eveytime
