Might be your fuel pump itself.

Question is, does fuel pump relay come in/ go out when ignition switched on? How do you know "no power source to fuel pump", was that because bypassing the relay didn't cause it to run? Or did you check for supply to the pump and find nothing doing?.
Sounds rather like a frozen pump to me... or a blown fuse??

Check to see if you have spark to your spark plugs. On hondas if you have no spark it wont let the fuel pump get power. This is controlled by a small part in the distributor called the ignitor by honda and ignition module in aftermarket terms. when this part goes bad you wont have spark or fuel. it is a pretty expensive part. sometimes its cheaper to get a used distributor at the junk yard and change the whole thing. also make sure your timing belt hasnt snapped cause if it did your distributor wont turn and you will get the same results. take the distributor cap off and check and see if the rotor spins while someone is cranking the engine. if it doesnt turn your timing belt is broke or your camshaft broke in half. broken camshafts are a common problem with 95 accords. If none of this helps you may have a wiring problem or even your cars computer may have taken a dump

1989 HONDA PRELUDE 2.0 HAS A CRANK NO START OR INERMITENT START HAS SPARK, IS TIMED CORRECTLY FUEL PUMP COMES ON BUT NO POWER AT FUSES 1,3


May need special priming sequence for pump. Haynes manual should have the proceedure. My van has a safety switch like that. Contacts have to be shorted for exactly 5 seconds with key on for mine to reset and prime in tank pump.

Why does my car not start?


You must find out if all the power from the distributor is getting to the plugs & the proper fuel PSI is being INJECTED into the motor (are the injectors INJECTING the proper psi at the right time or are the PLUGS FIRING properly? Poss? cam/ crank sensor, Not a steady Honda man but start w/ the basics. You got a reliable one there. check Fuel PSI, Air. Gas PSI, Spark & codes usually reff to electronic problems.

Fuel pressure regulator probabaly flooding it when you turn the key forward it primes but the regulator just dumps to much fuel into the cylinders flooding the plugs pull a plug out after you try starting it if it dont start and see if there full of gas

Welli have towncontry i change computer but dont start and the inyector dont have electricity to star the car


Is the computer powered up? Does your check engine light come on when you turn the key to on?
If that's o.k., check fuel pump operation. Do you hear the pump come on to prime the fuel system when you first turn the key to on? It should turn on for about 2 seconds, and then stop again until the engine is being cranked, at which time the pump comes back on. You can't hear the pump when engine is cranking or running, but you could hear it first come on to prime the system. There may be a schrader valve-a test port- on top of engine on the fuel rail. If you find it, take the cap off, and press down the valve-gas should shoot up if the pump is working and getting fuel to the engine.
Now if the computer is powered and the pump is getting gas to the engine, and still no start, you need to check your ignition system by checking for spark at one of the sparkplugs. Pull a plug wire off a plug, pull the sparkplug out, reattach the plug wire to the plug, and lay the sparkplug on a metal part of the engine, so the sparkplug threads are touching metal (grounding it). Now have someone crank the engine over while you watch the plug for a strong blue spark there. You need to see a blue, snapping spark to know your ignition system is good. An orange spark is not good-too weak. If no spark, or not consistent, you have a problem in the ignition system, and will have to diagnose and fix that.
If all is good so far, you may need to check the fuel injection system. Start by pulling one injector connector off, and check for power on one of the two wires going to the injector (the other wire is the injector ground wire), with the key in the on position. If no power to the injector with key on, the injector drive circuit has failed. If one wire does have power, post back to me for how to test the injector ground circuit-very easy with a testlight.
Good luck.

My mazda 323 b6 injecters are firering at the same time anf the cars does not start


Listen for the fuel pump to turn on with the key ON. Do you hear it buzz on for a couple of seconds, and then shut off? If you do, the pump is working. If you don't hear it, the pump is bad or the wiring to the pump is not working. Check the relay.
Usually, on a four cylinder with multi-port injection, injectors 1 and 3 fire simultaneously, and then injectors 2 and 4 will fire at same time (because their ground wires are spliced together before entering the computer. When the computer internally grounds the wire, the injectors will pulse). Are you certain that all four are pulsing at same time? If so, that may be the Mazda way. But I think you are right to believe it is a fuel problem. Test the pump as stated above, key on (not start) and listen for pump to turn on.
Good luck.

No fuel up to injecter pump truck just stalled


Did you check for fuel pressure on the line from the tank while you had the filter off? Do you hear your fuel pump prime when you turn the ignition on? First I would listen for the hum of the fuel pump when you turn the key to the run position (not starting the engine) May have to get a helper and listen at the gas filler neck with the cap off. If you dont hear your fuel pump, check your fuses and relays. If the relay clicks when your helper turns the key on ( put your finger on the relay and ear down close to feel/hear the relay actuate)., and fuse is good, yet you do not hear the pump prime, I would say your fuel pump is shot.

If it is a diesel,check for fuel pressure coming off the direct drive pump hose while cranking the motor.

I have a 1989 iroc camero that will not start.it has a throttle body carb and is a 305.the fuel pump works fine.the car will start if you prime it,but otherwise it wont fire at all.it has power on one wire...


Although you Say the Fuel Pump is Fine, What you Discribe is A NO FUEL Problem If it Starts When Priming and Does Not Without Prime this IS a Fuel Pump Problem NOTE: If you HEAR the Fuel Pump this only Indicates that the MOTOR that Drives the Fuel Pump Works , A Fuel Puessure Test Will Determine if your Fuel Pump In FACT DOES Work.

1995 honda civic d15b7 cranks but wont start. new


Are you sure you have correct timing? its definetly a fule problem, if timing is good then turn your key to the on position and try to listin for the fule pump to prime. While the key is in on position go to fuel rail, there is a valve on fule rail called sharader valve. Get a small screw driver and press valve in to check if car has fule pressure. if pressure is present then it is incorrect timing or possible bad cam sensor.

On fuel injected cars just turn the key on you should hear the fuel pump run for a few seconds turn the key off then back on. Also make sure the injector harness is plugged in.
