how do you tell if fuel pump is bad

[DETROIT SHOMAN]

i have scanned this car three times and no codes are present but the check engine light is on and it has hard starting when hot could this be a weak fuel pump also when driving is had a stumble at 50mph

If the check engine light comes on, the computer does store a code.

If you retrieve it improperly, you will erase it.

Double check your procedure.

PS Stay in your original thread, don't start new ones unless it's for a different subject.

i just got back from the dealer and he scanned the car and the code numbers are 111 10 212 214 are these fixable code now and what do i need to replace to get this car to be right thanks

The 10 code doesn't make any sense. You either get all 2 digit codes or all 3 digit codes depending on the year. I believe 93-95 are 3 digit codes. Go here http://www.shotimes.com/SHO3eeccodes3.html to found out what the codes mean.

The 111 means everything is fine, so it doesn't make sense how everything would be fine and then there would be additional trouble codes.

Anyway, after double- and triple-checking the codes, if you're sure there's a 214, that points to a faulty Camshaft IDentification sensor. Yes, I capitalized CID intentionally.

Make sure, really really sure, you don't have a 211, as this typically indicates a bad Crank Position Sensor (PIP).

As previously mentioned, you can't have a code "10" on anything '92-'95.

Your symptoms, trouble starting when hot, are very similar to mine when my CID sensor went bye-bye. Luckily for you it's a cheap and easy fix!

Good luck.

you can get a 111 and then have codes. the 111 just means that everything went fine in that portion of the test but then the test continued and there were other problems.

My apologies. I've never, for example, gotten a 111 and also had a trouble code, so I didn't realize this could happen!

Steve, you own a SHO. First thing everyone needs to learn is throw out all reasoning with the car!!!

Your fuel pump is bad when it stops pumping fuel thumbs_u
