timing belt?

No, but it can cause a newsgroup participant to wonder what the HELL you're doing running a timing belt for 140,000 miles.

well the car was running great until the fuel pump went. i am getting it changed because you are correct with your ? :-)

Might I ask where in Wisconsin you are? (my e-mail is valid)

check the compression. Poor compression in all cylinders would indicate a jumped timing chain. I guess it would indicate the same for a timing belt. Also if you just replaced the fuel pump maybe that's it. i think there are a lot of bad ones straight from the factory. check your fuel pressure.

Yes, sure.

Sure.

Not without replacing the timing belt, which you know is bad just from the fact that it has 140,000 miles on it. Fix that and you'll be able to start diagnosing anything else that might be wrong.

thanks for the replies guy's. i had a bosch fuel pump put in because the parts house recommended it over a cheaper brand. i got this car back from a garage after a week and the owner said he ran all kinds of tests on sensors,cat converter, used a scan tool, etc. fuel pressure test, and all he found was the timing seemed to jump a bit on his scan tool. this has been going on for a month now and i don't know where to take it anymore. :-(

Okay, so think to yourself. What could the collateral damage from a bad fuel pump be? You could have dumped some debris from the fuel pump into the regulator. You could have stretched a marginal timing belt from the engine bucking. You could have damaged an engine mount and torn a sensor cable loose from the engine bucking.

When you replaced the pump, did you check the rail pressure at idle with the new pump? I'd do that next, after changing the belt.

That's probably good.

You could try the dealer. But what worries me is that if you have gone

140,000 miles without even changing the timing belt, what OTHER maintenance have you been putting off?
