Try running the fault codes to find the fault rather than guessing and wasting money. After all the CPU stores the faults in a memory waiting for them to be read and fixed.

SOURCE: car is stalling and idleing irradically.

I Would Suggest That You Complete A Engine Cylinder Leak Down Test.....(not A Compression Test But A Leak Down Test) this will tell you if you have internal problems....possible worn rings or a burnt valve(s) I would use a smoke machine to check for vacuum leaks also. Good Luck

SOURCE: 1989 GMC 2500 5.7L - engine surges and stalls at idle. Loses power at cruising speed.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

Check throttle position sensor (TPS) is a sensor used to monitor the position of the throttle. The sensor is usually a potentiometer, and therefore provides a variable resistance dependent upon the position of the valve. The sensor signal is used by the engine control unit (ECU) as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending upon the position of the throttle, and also depending on the rate of change of that position. For example, in fuel injected engines, in order to avoid stalling, extra fuel may be injected if the throttle is opened rapidly (mimicking the accelerator pump of carburetor systems). the cost about 50-75 bucks.

I have a 1998 Volvo S70. In cold start up, car runs 15 seconds, then dies out. It won't start after that. I've cleaned throttle body, cleaned out air induction pump, and replaced air pump relay.


Does the car throw a check engine code? If so, what is that code?

This could also possibly be the ignition. My V70 had a bit of trouble on a couple of cold mornings. I replaced the ignition switch (located in the steering column on the opposite side of the key hole).

Also check the fuel pressure and fuel filter. Could be a pump and filter problem. Fuel condenses at lower temperatures and if the pump is having issue pushing the thicker fuel through the filter, take a look at that to be an issue.

Lastly, check the throttle and the fuel injectors. Run fuel system and injector cleaner like HEAT through the fuel tank to see if it helps.

Fuel injection relay. It is located under the hood inside the fuse box. It is either red or green in color. It is one of the larger relays. This is classic symptom of these things going bad. The heat causes the relay to swell and not engage properly. They die out every couple of years. Usually the car will start again after it cools down.

CAR STARTS THEN DIES OUT, WHEN IT IS RUNNING WHEN YOU GIVE IT GAS QUITS RUNNING. CHANGED FUEL FILTER AND AIR FILTER HAVE A HALF A TANK OF GAS


you could have a bad MAF sensor...try unplugging it and driving it around and see what happens. also make sure airfilter is clean. check fuel pressure if above does not work! the fuel cut valve may be the culprit. if it is the maf sensor, you can go to any auto parts store and buy a can of maf sensor spray to clean it. just follow directions on can. do not hit center of maf sensor with the straw on spray can, for these buggers cost over 100.00 new. unless you get one from e-bay or a junk yard. good-day! and check all vacuum lines good.

it could be a couple of things going on, the fuel filter may need to be changed, plug wires may need changing, the mass air fuel sensor may need cleaning or replaced. I would go with a tune up: change spark wires, distributor cap and rotor, chang fuel filter and air filter. doing the latter may cure your problem

I'm having the same problem. At first I thought it was bad fuel so I replaced the fuel filter to no avail. Then I cleaned the Mass Air Flow sensor which also didn't work. Is your check engine light on?

Son-in-law did a tune up. Plugs, plug wires,


Do a quick check. Run a wire passed everything from the battery positive terminal to the power connector on the pump, or if you cant get to the pump directly then the first connection you can make to the pump's power supply wire. If she fires up then its a bad fuse, faulty relay or something electronic not putting the power through. If she still refuses to fire it could be the fuel filter filter (to lean), leaking fuel regulator or leaking injectors (too rich). the regulator has a vacuum line on it. If there is a leak in the regulator then fuel vapour is carried by the vacuum line and enriches the air in the intake manifold. The fuel pump has to deliver about 40 - 50 pounds of pressure to the fuel line and has to keep about 90% of that pressure for about 5 minutes after it has been switched off. Dropping pressure indicates poor valves on the pump or leaking injectors. It is not enough that the pump is effective the fuel line should be capable of filling a pint pot in about 15 seconds. If the pump has good pressure (and retention when off) but poor flow then the filter is clogged (this will also kill the pump eventually). As a final check make sure the idle air control valve on the throttle body is clean and functioning as it should.

Check for an air leak in the fuel system. It sounds like the son-in -law did good work but missed an air leak somewhere. The system is not providing enough fuel to the engine. The other possibility is that you are pulling a vacuum on the fuel tank. They have to be vented either through the cap or through the canister. First take the fuel cap off and see if the truck will run. If it does put the fuel cap back on and pull the hose off the canister and try to run the truck. If it runs it was the canister.

2000 volvo s70 difficult to start, more so as fuel level drops. Cranks fine. Recently changed MAF sensor, B+ cable, plugs, fuel filter - no improvement.


Sounds like the fuel pump, as the levels of the fuel tank drop, there's less natural pressure on the fuel, which would definitely make it harder to start with a weak fuel stream from a bad pump.
