Did you replace the fuel filter, and do you know for a fact the pump is getting power and ground when you turn the key switch on ?

Try checking the engine mountings

Which size of the engine?

I don't usually do diagrams due to copyright laws. From the fuel pump you have a gray wire and a black wire.The black is ground and the gray is power from both the pump relay and the oil pressure switch. The oil pressure switch provides power to the pump once the engine starts.At the relay, you have a green and white wire that provides power from the ECM with the key switch on. You have an orange wire that provides power from a 15amp fuse. The gray wire going to the pump, and a black and white wire for ground for the relay. The ECM provides power for 3 seconds when the key switch is turned on to boost line pressure for startup.

common problem is cluster. tap on cluster see if light comes on. if not cluster needs to be sent in for repair. vehicle will not run when cluster is removed..

sounds like your lock rod clip broke, have to remove door panel inside and release it to open then repair lockrod

The bulb on the check engine light may have failed. Pull out the dash instrument panel and check light condition from the rear.

There is a small vacuum hose that runs along the front of the throttle body.Usually gets brittle and brakes .This runs to the passenger side of the firewall this goes to the heater box.without vacuum the valve under the dash can not switch.I hope this helps

Yes, I never did like ABS brakes because of this. What you have experienced is the ABS system working as it is designed to do. I know, it doesn't seem like you should still be moving after slamming on the brakes, but here is how it works;
When you apply a fast and hard pedal and the ground beneath you is wet the wheels stop at different times. There are sprockets mounted to the rear of the rotors, with magnetic sensors that monitor the wheel info. for all four wheels mounted next to the brake calipers. On a hard stop when the sensor detects one wheel stopping and another still going, these sensors send "pulses" to each wheel until the vehicle has stopped without the brakes having to lock up. The pulsiing is what you experienced and is a normal part of the ABS function.
Please rate this and let me know if it helped.

Duplicate question.

No fuel pressure.

If you have the commercial model with the square headlight bulbs, the trim ring comes off.If yours takes a regular bulb that is made onto the base, it comes out from the back.

Someone would check for voltage and a ground signal at the coil, then backtrack to the distributor.

Sounds like you have a drain. Take off the positive battery post,and hook a test light to the unhooked positive battery cable. Then touch the end of the test light to the battery positive post on the battery,...if it lights up,with the key off,and all doors closed,then you have a system draw. Start pulling fuses untill the test light bulb goes out. When it goes out,use your manual to see what that fuse operates,and that will narrow it down for you. Good Luck!
