Wont start


Are you able to perform a fuel pressure test? If your filter is getting clogged, pickup in the tank, etc. it will allow fuel to flow - and you'll have proof at fuel rail - but...for instance - my 87 K5 Blazer runs on about 8 pounds of pressure. Hardly any. That 8 pounds doesn't make it to the throttlebody? Out of luck. I had this issue when I first got it. Gas was present - but not enough pressure. It was at about 3 pounds or so. Enough to send it down the fuel rail - but just not enough to get and keep it going. Based on what the symptoms - before I went too much further - you can buy a fuel pressure/vacuum at Advance Auto or any others for about - $20 - $30. Most come with the universal parts to attach to the fuel line - and you'll have rock-solid evidence of that fuel pressure/pump's functionality. If you test it - all's good/still no start - just comment and I'll go further with you -

1991 ford bronco fuel pump wont shut off


The fuel pump should turn on for about 3-5 seconds when you turn the ignition switch to on. If the engine starts the pump should still continue to run, if you do not start the vehicle the pump will shut off. It sounds like your fuel pump relay is stuck. Sometimes they will stick on even with the key off. The relay should be located in the relay box, under the hood on the drivers side on the inner fender well. You can try tapping on the relays with a end of a screwdriver, etc. See if that does anything for you. If that doesn;t help I will have to look up some info. Been a while since I had issues with that .

Need to find out if there is spark while cranking first. Check at the coil wire first then at a plug wire.If there is spark at the coil and not at the plug the fault is the rotor or dist. cap.If there is no spark at all,suspect the ign. module. If there is good spark move on to the fuel pressure check.It needs about 40 lbs. to run.

1999 saab 95 would not start.i was not getting fuel, checked the valve on injector and no pressure. removed fuel pump and jumped motor and motor run good.turn on key and pump runs 5 seconds. could it be...


Fuel Pump relays are designed to run only momentarily until engine is running.Even if fuel pump runs it probably won't maintain enough pressure if you had no fuel pressure at the fuel rail.Sounds like a new pump is the ticket.

1989 Bronco fullsize has sat for the past 6 years and wont start, will turn over, has new gas with fuel stabilizer, still no firing. Replacing spark plugs and the fuel pump are the next two steps. ...


Assuming she ran good before she sat, replacing the plugs, cap and rotor isn't a bad idea.Step 1: Make sure you have good spark. No need to worry about timing right now. Step 2: If you have spark, then we have to see if its getting gas. There are two fuel pumps on this Bronco. One in tank and one on the frame rail. Can you hear either one running? The in tank one should come on for a few minutes and shut off. The front one is harder to hear.If you hear it, borrow or rent a FUEL PRESSURE GAUGE and check your fuel pressure. There is a fitting similar to a tire valve on fuel rail. Pressure should remain constant.If either pump fails you will not get adequate fuel flow. The front pump is easy to get to for trouble-shooting. Don't buy anything unless your sure you will need it. Hope this helps.

Could be fuel pump, is the pump running when you turn key on, you should be able to hear it. You are likely going to have to take it to someone with a pressure gauge to make sure it is getting proper fuel pressure. Fuel pumps commonly go on these vehicles

1989 Ford Bronco 5.0 engine will not crank. Replaced fuel filter and fuel pump, but still will not start. Engine turns over and will try to crank with starting fluid.


Timing is everything. Try testing you PCM. It's the little gray box near the base of your distributor. If you have spark, and fuel at the rail (plus good fuel rail pressure) than the timing is your problem.

Check the pet-**** on the fuel rail assembly to make sure the fuel at the rail is under presure and getting to your injectors. Then again make sure you have spark, lastly you should be able to test the trouble codes to see if your PCM is the issue.
Goos luck.

CANT FIGURE IT OUT


Is the fuel pump running? Take the gas cap off and put your ear by the filler. Now have someone turn the key to the on position (not all the way to start). You should hear the fuel pump run for about 3 seconds. If you don't hear the pump run, the most likely culprit is the fuel pump itself. Second possibility is the fuel pump relay.
