check fuel pump and relay

in fuel pump inside fuel tank

underneth driverside about in middle of car once under car follow fuel lines to it to help.

On pre-1996 import cars, you use a wiring plug under the hood or access the computer to make the check engine light flash the codes. You can do an internet search for "retrieve trouble codes" for your make and model for details.

Do you have normal compression, spark, and fuel pressure ?

there is a relay, it is most likely under the hood, in a black box with a diagram on top of it. On the left side of the block (the left most thing) is the relay, it is labelled

Sounds like the fuel pump is not coming on. I recall an owner stating there is a common problem on your model excel having to do with possibly an internal short in the ecu, or a connector problem with the pump signal wire at the ecu. I would have a qualified shop test the wiring for the pump.

Are you sure it is for the parking brake ?If the master cylinder is low on brake fluid the brake warning light will come on.

their should be a screw some where on or near the caruburater loosen the screw but dont over loosen it, one little turn goes a long ways. i hope this information helps, Be careful and drive safe!

It's either the wheel bearings going bad, or if the brakes are hot, the calipers are sticking, replace them and the brake fluid to keep problem from coming back.

Without actually inspecting/looking at the vehicle, the problem sounds like it's the Throttle position sensor (TPS). Before buying this component, you need to 'bench-test' it to be sure. The TPS is merely a potentiometer (variable resistor - POT) with center tap and two wiper plates (when the throttle is fully closed, the resistance in TPS A is at maximum and in TPS B is at minimum. When the throttle is wide open (W.O.T. - wide open throttle, the resistances of 'A' and 'B' circuits are opposite each other - A minimum and B maximum). The computer (Engine Control Unit - ECU) uses/monitors these signals to adjust/manage the fuel map (fuel trims). Using an analog Ohm Meter, you can test the TPS (or contact someone who knows how), to check for bad spots (erratic resistance changes) in the POT. If the POT is bad, you'll most probably find the problem where the POT is in/near the "IDLE" position... since that's where you mentioned sometimes 'stalls' when you hit the gas.

If you have changed the coil Then its the crankshaft sensor is your problem.

Do you have an in dash tach? If so crank the motor over and see if it moves, if it doesn't then you may have a faulty crank sensor.

on the distributor

probaly coil or ignition module,take the module out and have a auto parts check it,or see if you haver power going to the module and coming out same with coil,your module should be in the dist.
