98 tahoe put in rebuilt trans. now no fire to fuel pump wont start blowing fuses

You need to clear the codes first. Check fuel pressure.

Try jumping the starter with the key on. If it doesn't blow. Check the start wire for chafing and grounding out. You can pull the starter relay, Try to start it, see if it blows,yes, it is between the fuse panel and fuel pump. no. Put it in and pull the fuel pump relay. Start it. If it blows, then it is some where between the fuse panel and starter. If you have one of those intelligent fuse panels, it could be that also. You can have the codes read for it. But it takes a scanner, not a code reader.

Sounds like a fuel delivery problem. Has the fuel filter ever been changed? You can try banging on the bottom of the fuel tank with a blunt object ( hammer works ) while some one cranks the engine. If it starts suspect a bad fuel pump

When the truck wont start, bang on fuel tank to shake the pump. If it starts, replace fuel pump. 60 psi is what you should see with good pump. Less than 55 it wont start.

Have you tested fuel pressure? If you have no pressure the next step would be to test all relays and fuses. Next jump the fuel pump and see if the pump kicks on. If not, bad fuel pump, if it does fire, then the security system might be disabling the pump. Make sure all fuse and relays are good b

Either it is not getting fuel into the cylinders OR the spark plugs are not firing. Could be defective ignition switch, blown fuse to the fuel pump, blown fuse to the ignition, bad connection somewhere, you failed to pay for your permit to drive from the Homeland Security Bureau

short in the pink wire that runs to the fuel pump and it is most likly pinched.

Adjust the gear shift cable so that the park position sensor will move to the right position then it will crank. Right now it thinks it is engaged in some gear.

A fuse will blow for 2 reasons . 1) If the device has a Short in the circuit that runs through this fuse. 2) If the device draws more amperage from the power source through the fuse than the fuse will handle. ex. if a fuel pump or starter has a 20 amp fuse and the starter/fuel pump is going bad and draws 30 amps it will blow the fuse. A fuel pump on a 1996 vehicle is located in the fuel tank and is kept cool by the surrounding gas and the gas that flows through it. Overheating a fuel pump is virtually impossible. That being said there is a High probability that replacing the fuel pump and relay will fix this problem. It is quite common for this to occur in the GM vehicle of 1996. When the pump starts to fail, it draws an excessive amount of amperage and would blow the fuse. Hope you find this information useful.

Hope you got a good deal on that oil change. do you believe in coincidence. I can't imagine how an oil change could do anything to stop the engine from starting. So you have to rule out things like starter and fuel pump. to check the fuel pump go to a parts store and buy a can of starter fluid. Remove the top pf the air cleaner box. Have someone spray starter fluid into the opening going to the engine while you are trying to start the motor. If it fires up the pump is bad if not go on to the starter. For the starter locate the relay under the hood (in a fuse box) labeled for the starter. Remove it. Then run a wire from the positive terminal of the battery (careful not to ground to car) and touch where the relay plugged in. One of the points should kick the starter over. If none of them do i would suspect the starter. if all is ok the next possible suspect is the computer. You will need a dealer for this one but some computers have extended warranties because of problems so ask the dealer about it. I just had one replaced for a customer last summer on a 2001 Chrysler T&C and it was covered under warranty. Whole visit was around $200 If this helps please reply and good luck
