HPOP?? what gives...

[Razec]

First let me say hello to everyone on here. this is an awesome site loads of info.
im the proud owner of 97 stroker 265 thou on the clock, my problem is darn thing just shut off on me like turn the key off, off. went through the usual inspection and replacing of cam position sensor, fuel filter removing the chip to no avail the truck just will not start. my batts. are good glow plugs good oil level good in hpop.

guess my question is could my hpop have gone bad just like that or might i have another problem? could my injector module have gone bad?
I know im not getting any fuel to the cylinders cuz no smoke or any fuel out of the exhaust that i could smell. tried starting fluid it will start but dies...
any help would be great thanks. once again this site is great.

oh yeah i only get a lil drible of fuel from the shrader valve when i release the pressure while my girl cranks on the ignition..

Could be the fuel pump in the fuel tank. Or the fuel screen is clogged up in the fuel tank. I would check and see if the fuel supply pump in the tank is working. When you turn the key on you should hear it buzzing for 3-5 seconds as it builds up pressure.

did'nt think 97s have a fuel pump in the tank? i'll check it out thanks.

It may not be in the tank it maybe on the frame rail. Either way I would be checking the fuel supply pump. If it is not working properly then your fuel pressure would be down. Also I am not sure where the main fuel filter is at but if that is clogged it will cause your problem as well.

on a 97 model truck, the fuel pump is mounted in the engine valley ,you need 55-60 lbs of fuel pressure , if you are only getting dribble that is very well your problem, a standard fuel prssure gauge will work to check, as you crank it should gradually build to 55-60, there isnt a fuel pump anywhere else on this vehicle

97 fuel pump is in the valley of the motor, a B*TCH to get at too.

yea didnt think there was one in the tanks. no joke on replacing the pump had to bend a wrench several directions to get the rear fuel line on my last stroker when it developed a leak..got it done without removing the turbo. a bit of a chore...
whats the actual job of the injection pump? i know it pressurize the fuel the fuelpump brings to the filter.
does it go tank,then filter, injection pump,then injectors or; tank, injection pump, filter, injectors??

Should be tank filter, fuel pump, injection pump, injectors.

ok did a fuel pressure test 45/maybe 50 lbs of fuel press. is that enough to runn the truck???

It may run with that much pressure but it is not going to be driveable.
