starter fluid?
Expert:  proautotech replied 2 years ago.

Customer: replied 2 years ago.

oh sorry was so focused on the vehicle wasnt think outside my rig...duh


ok i can get some. now what...:)

Expert:  proautotech replied 2 years ago.
We need to spray this into the throttle body. Just disconnect the air filter spray it inside the hose. See if it will fire it will die but it should fire up for a few seconds.
Customer: replied 2 years ago.
i have a k&n airfilter kit installed so where would i need to disconnect..
Expert:  proautotech replied 2 years ago.
That tube goes to the throttle body assembly. This is the intake tube. Anywhere behind the filter will be sufficient.

Expert:  proautotech replied 2 years ago.
Okay grab 2 cans if you can. Just in case!
Customer: replied 2 years ago.
ok ...well it started for a second then died....
Expert:  proautotech replied 2 years ago.
Okay. You have a bad fuel pump.

Would you like the steps to replace?
Customer: replied 2 years ago.
i had my fuel pump changed about 2years ago is this a part the fails often..could it maybe be the relay or anything else that is nit such a pain to change..
Expert:  proautotech replied 2 years ago.
Not likely.

But you can verify the power is getting to the fuel pump if you have a volt meter.

I suggest going to amazon and getting a fuel pump overnight it for half the cost that the dealer and napa charge.

The fuel pump only turns on for a few moments when the key is turned on. So you will need someone to cycle the key while checking with a voltmeter. Going into the relay you should have battery voltage on the light blue orange wire at all time 12v on red when key is cycled on. Than it should have voltage going through the dark green yellow wire which goes to the inertia switch.

I myself would go right to the inertia switch check for power coming in on dark green yellow wire and going through the switch to the fuel pump on the pink black. If so you can be certain the wire is giving power. You would have to drop pump to verify it is getting voltage.

The inertia is behind the passenger kick panel pull panel off to gain access. CLICK HERE FOR IMAGE
