I hope someone can help me,

I tried to pull the codes, but no luck i did exactly what haynes said to do and my check engine wont flash it just stays on, But i can hear the relays and shit clicking.

I tested the fuel pumps..and yep there workin alright and i got 43 psi on the rails, but to my dismay, no fuel into the cynanders. What causes the injectors to open? could i need a new computer...

Thanks Mike

To pull the codes, i did exactly what that website describes (i even took my comp. outside so i could follow them to a T) and i hear the relays and stuff....but the check engine light just stays on. Im gunna give it another shot tommorw morning just in case.

As for the fuel pressure, thats right in the specs.
I also picked up a set of noid lights at work today...ill post the results tommorw...

By the time I get done with this ill have the tools to fix any fuel problems for the rest of the Bronco`s Life :banghead

Ok, I pulled the codes and actually got something today, i have a 21, 22, 24.

According to the haynes, Its

21- ECT Sensor out of normal range
22- Map sensor out of normal range
23- ACT or IAT out of normal range

Now that i have these, im kinda wondering my next step, As to why this truck wont run, if anyone has ne ideas please let me know.

21 = ECT out of self test range 0.3 to 3.7 volts.
Was the engine at operating temperature?

22 = MAP/BP sensor out of self test range 1.4 to 1.6 volts.
Test the MAP sensor.

23 = Closed throttle TPS voltage higher or lower than expected.
Test the TPS

Multiple threads are bad. Keep it all in one thread.
It gets verry confusing whene there are multiple threads running about the same proplem.
