SOURCE: 1999 Honda Accord won't start. No fuel pressure,

The relay may be located in the under hood fuse/relay box.
Check your manual for the location of the relay, if listed.
Check for a sticker on the inside of the under hood fuse/relay box for a possible guide.

If you think there is fuel pressure just because the fuel pump kicks in, you might not actually have pressure. The fuel pressure regulator could be shot which would cause the fuel to go right through the fuel rail and back into the tank. So make sure you use an actual fuel pressure gauge to test that and rule out the pressure regulator...just had to make sure you did that.

If you do in fact have fuel pressure, spark, and compression, then the issue is either your timing or that the fuel is not getting inside cylinder. Timing fix is obvious, the issue with your fuel could be clogged injectors, bad injectors, or the injectors are just not getting the signal to fire. The latter is the most likely. Use a mechanics stethescope and hold it to one of the injectors and listen for a clicking sound when your cranking the engine over. You can pick one up at harbor freight or sears. You could also take a screwdriver and hold it against the injector and press your ear against the handle. However, if the engine shakes while you crank it you might have a very bruised ear...try explaining that one to your friends. If the injectors are not firing, the resistor pack is probably bad. The resistor pack is that thing on the drivers side of the engine compartment with the heat sink on it. Pick up a new one from a junk yard if you want to save a few bucks. That should fix your problem though.

I have a '91 oldsmobile corral 3.3L. Acts like it's getting to much gas. When it starts,runs fine. New fuel pressure regulator and oil pressure switch. Now won't start,any ideas?


When the problem is ongoing, if it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check for a fuel injector pulse.

No gas coming out the injector and there is gas pressure to the injector?


Is there an injector pulse going to the injector?(an electrical pulse to fire the injector).
Is there spark at the plugs?
If the pickup in the dist is faulty you won't have either one.
If your vehicle uses a crank pickup with or instead of dist pick up....if it is defective ....no pulse.
The above is 90% cause of no pulse....other is computer problem 10%.
If you do have a injector pulse and no spray.....and have fuel pressure....change the injector.
A quick check for spark is spray a little starting fluid in it.....if it starts on the fluid....spark is present.

Crank no start: has no spark and only has injector pulse on cyl # 1. if you spray starting fluid directly into throttle body car starts and stays running and has spark and inj. pulse. once you turn the car...


Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.

No start


if it runs on starting fluid its a fuel problem.. check fuel pressure even if its a couple of pounds off, the vehicle will not run. but using starting fluid may give you the extra poundage you need to make it run . also check vacuum hose at pressure regulator on fuel rail
