What ever you do, do not, I repeat do not take the lower radiator hose out of the car. This breaks
the VATS circuit and you will never get you car started. You will need to by a new VATS program box for up under the dash. This will cost tons. Radiator hose distributes 50mhz wave signal to the
VATS box. Removing this hose with short circuit the VATS and passkey and passkey II systems.

Otherwise, sheck you battery for 12 volts and 600 amp rating.

So my fuel pump has been making a high pitched noise for a while. Then one day, without warning, I tried to start the car but it wouldn't. It cranked but would not start. I turned the car on (not start)...

I looked at info for 3.1L vinM Buick regal. fuel pressure key on engine off, 40.5--47 psi. Can you check the vin? The fuel pressure specs I have for 3.8L engine are even higher than the 3.1L.
You will get a fuel pump prime, key on engine off. You need to make sure fuel pump runs with engine cranking.
My hearing is no good, I can't hear fuel pump with engine cranking.
Sometimes If fuel pump brushes are bad, the fuel pump may run intermittently. Sometimes you can bang on bottom of gas tank when trying to start and the fuel pump will take off running.

The fuel gauge on my '88 Buick Regal limited is not working. I'm not sure where I should start looking, in the dash console area or the fuel tank itself. Any advice as to how to go about repairing it?

It sounds like a problem with the fuel gauge sender unit in the fuel tank which is has worn out and gone open circuit and needs replacing.

Fuel& Temperature Gauges are sticking Example gas tank full of fuel but only reads half full, temperature reads hot but engine is running at normal temperature What is wrong and how can we fix it

they could be seperate problems. the fuel level sender in the tank may be bad. the 2 wire coolant temp sensor may be faulty. there may be a bad ground some where or a bad connection in the harness. although it is common for the circuit boards in the cluster to go bad and you get funny readings on one half or the other. i would start diagnosing the cooling problem first. those engines have an air bleed valve above the t-stat. make sure there isnt a pocket of super heatad steam in the system (first indication of a small leak). the cts also controls the fan relays through the pcm. are the fans comming on as the temp guage passes half way? what does the guage do when the key is on, engine off, cts unpluged, and the connector jumpered or grounded? the guage should have a full sweep if it doesnt sweep the cluster or harness are suspect

'91 F150 won't start

I guess there could be debris in the tank - but the fuel filter will catch it and clog up (is that a hint, or what),

Other possible is the ignition coil... the are plastic inside and they dry out and crack inside.... when they are hot - open circuit... When they are cool, closed circuit - working...

so, next time it dies, check for spark. Otherwise, replace the fuel filter (hopefully you have one OUTSIDE the fuel tank).
Let us know - please... -Jim

1992 f 159 dual tanks fuel guage not working

You will need to remove the wire for the sending unit on the tank and ground it to the frame with your selector switched to the tank you are working on and the key on. If gauge comes up to full then the sending unit is bad and gauge is good. Repeat process on other tank. The fuel tank switching valve on the frame also switches the wiring signal from either tank for the gauge. If no change with first test you will want to check the valve.

Car wont start

This vehicle could also have a crankshaft sensor failing. When it dies next time, if you don't have a fuel pressure gauge available, and can't rent one from a local parts house, try tapping the bottom of the fuel tank with a block of wood. If it restarts immediately, then you may well have a fuel pump problem. Don't hit the tank so hard you bend it, and don't use a sharp object, as you may puncture the tank. If this does not work, you may need a scan tool to access the data stream to check for the crank signal necessary to make the engine start and run.
(Fuel pressure on this vehicle may be in the range of 38-60psi, do not push in the valve on the fuel rail to check for fuel pressure on a hot engine, or while spinning the engine over, you may start a fire)
