so my truck just wont start at all anymore, will crank all day but no start, it has spark and ran great until today... i pulled the main fuel line off the rail and cranked it over for a few seconds and no fuel was coming out at all. also the plugs were completely dry after cranking it for atleast 10 minutes trying to start it.... so im going to buy a fuel pump. do i need the bracket and everything or just the pump ? were can i buy one? also im going to replace the injectors while im at it...

Before you spend all that money maybe figure out just what is wrong.

Will you need a fuel pump bracket It is good to have a new one lots of times things break taking it apart.

Last I looked new fuel pump brackets only came from the dealer.

This after all is your truck if you want a new fuel pump and new injectors go for it.

Most common issue is the Air flow meter (AFM) not working correctly. There is also relaya and fuses to check before replacing fuel pump. Do a search on this site and you will find a wealth of information. There is a procedure to install a jumper wire in the diagnostic port to supply the fuel pumo with battery voltage. This will tell you wether or not its your pump or the circuit.

ok ill do some research thanks

also to add ive had a running lean CEL for the longest time and it wont go away, ive already put in new fuel filter

You could have one or more of the common issues for a lean code. A O2 sensor not reading correctly, a intake gasket leak, a vacuum leak, or a faulty injector. Or it could just be from so much crank time with no fuel, but not likely.

With the key on and Fp +B jumpered with a paperclip, can you hear the fuel pump on?

The Circuit Opening Relay is also involved in the circuit. I do not have any info on that but 4Crawler does.

Fp +B Fuel Pump Test for 87 and newer. Use a paper clip for better results.

ive checked for 02 sensor reading correctly with a tool in autoshop, alse used a smoke machine for vacumm leaks. ill try the fuel pump test thanks alot man

well i put the paperclip in the fp and +b and turned the ignition to on and not a single thing happened, i guess my fuel pump took a dump

also does my key need to be on when the ports are being jumpered or does it need to be cranking with the ports jumpered?

Either rhe fuel pump or a short in the harness. Drop the gas tank and then check for power at the fuel pump connector and also chexk for continuity on your ground circuit. If both of those check out then yeah time for a new fuel pump.

why do i drop the tank? the connector is easily accessible. weres the ground circuit?

92yoterDD

If I remember correctly its in the same connector. I said drop the tank cause I forgot how easy the plug is to get to.

ok. how many volts should i get to it while cranking?
