I have a 1988 camper it's on a Ford F350 chasse with a 460 ci. engine. Has one gas tank with a low pressure pump in it and a high pressure pump on the frame rail. The truck runs for an hour and dies. at that point there is no fuel pressure or spark and the high pressure pump is hot. I replaced the high pressure pump and the fuel pump relay but it didn't help. Can anyone tell me why the high pressure pump could be getting hot and would it cause it to not have spark ?

Guess I entered my problem in the wrong forum, I need a fuel pump relay diagram for a 1990 740 GL. I live on a dirt rd, the main pump/ filter bracket filled up with mud and fried both pumps. Guess the in-tank pump was weak. I am converting to an in-tank high pressure pump (regina style) also relocating the filter ti the engine bay. I cannot get the pump to come on when the switch is first turned on (prime) works good when engine is cranking.

I have a 2001 Chevy blazer extreme, I have replaced everything. Fuel pump, filter, and fuel injection spider. None of these were the problem, when I turn the key to the on position, the fuel pressure gauge climbs upto 2 psi. After the pump cycles the pressure drops to 0. If I prime the system the pressure will climb to 10 psi, then promptly die off as the engine stalls out again. I have changed the pump twice just to find out the problem still exists. What am I missing? I have no engine codes th

1994 Caravan 3.3L replaced fuel pump with junkyard unit from a different year, now truck stalls at low speed driving (idles OK). Tried direct wiring pump (no relay), I can solve this by interrupting electricity to the pump for a few seconds at intervals. Does the replacement fuel pump have too high pressure? Does the pump relay cycle in operation to control pressure?
I wouldnt have put in a used pump especially with all the work needed to put it in. And one from another year is definitely not recomended because we dont know what each years flow rate is. Also chech your fuel pressure regulator as this should be co ... 2004 Dodge Grand Caravan

Fuel Pump I have a 2 c turbo diesel engine thats about more than ten years old.

I have replaced the low pressure fuel pump, the high pressure fuel pump, and fuel filter. The relays are fine and the check engine light comes on so the EEC is ok. It will turn over but will not start. I have gotten it to start for about 10-30 seconds but then dies. Also, my battery is about done but will jump start a few times but will die within seconds.

I can't find the fuel pump fuse for my 95 SC2. I want to replace the fuel filter, and I'd like to release the pressure on the fuel line by pulling the fuel pump fuse and then running the engine until it's out of gas. The under hood fuse box on the 95 SC2 shows all kinds of fuse labels, but nothing really looks like "fuel pump". I thought I'd be able to find a diagram on the web but not such luck. Any one know where the fuel pump fuse is?

Fuel problems 1999 Grand Prix GTP 3800 Supercharged VIN 1: car starts, but shuts down within 10 seconds. You can see the fuel pressure drop within those 10 seconds.

I have a 1988 Bronco II that was not driven for about 18 months. The gas smelled bad so I removed all the gas from the tank, installed a new in-tank fuel pump and high pressure frame mounted fuel pump and fuel filter. I also checked to see if I had spark and that seemed to be fine. Right after I installed the fuel pumps I could hear both of them engage when the switch was turned on. When I went to start it the next day I had no luck. I then replaced the fuel pump relay, even though the old

I've received the P0193 Code (Fuel Rail Pressure Sensor, High Input) on my Ford Escape (2005), I was curious what the most likely cause is for this issue, I've read some posts that say simply to replace the Fuel Rail Pressure Sensor (which is listed as one of 4 candidate causes); others include the fuel pressure regulator and fuel filter (already done) and fuel pump.
