What could have possibly happened.

in my earlier post I stated I went to start my car and noticed my fuel pump relay did not cycle. still cant figure why.

In diagnosing my problem I have now noticed I have no power at my TPS with ignition on.

I am beginning to think I have no power to the computer...but...
with key in ignition posn the SES light comes on and thier is power at the two fuses on the relay board(painless set up) one constant 12 the other 12 while cranking.

why no fuel pump relay power? why no TPS voltage?

any suggestions?

I am heading back out to look some more I will check back here for some advise in an hour

thx

I now have my voltage at the TPS. fuse was not in holder all the way.

still no fuel pump power? there is power to the relay 12 volts constant.

still looking for some suggestions

Fuel pump relay maybe? I've read of others who have swaped the MAF relay with the Fuel pump relay to try and trouble shoot problems. Not sure if it will work with your car or not. I would look at the wiring diagrams first before trying it though. Hope this helps.
