After dropping the tank twice to replace my fuel pump (which is a bitch of
a job) , I tried this. Removing the bed can be even worse. After thinking
about it, I should have used air or electric sheet metal nippers to cut the
How To Diagnose A Fuel Pump Failure - EricTheCarGuy
I had the privilege of visiting Airtex, and while I was there I spoke with
Shane Neuman about diagnosing a faulty fuel pump. In this video we go over
the basic steps of diagnosing a faulty fuel pump. So if your vehicle isn't
starting and you suspect a fuel pump problem, here are some steps to follow
to confirm your suspicions. Another 'quick' test is to bang on the fuel
tank and then try and start the engine. Sometimes this works, just don't
bang too hard, you could damage something.

Engine Running Problem

Truck is a 1992 Chevy K1500 5.7L TBI
This got me stumped. This truck has never had any problems before, and has
sat for extended periods of time with no problem. It sat for a couple
months, has had a tune up (coil, cap, rotor, plugs, wires and a fuel
filter) done within the last year. Also had a new fuel pump put in it when
all the other stuff was changed. After sitting for a couple months it
started acting up like this, stalling out in the road when I stop and
everything. Took the cap off and everything was clean, nothing was wet. All
the wires were seated properly and in good condition, plugs looked good, a
little rich but not bad. Then when I go to take video of it it clears right
up. Now it is just intermittent.
Do you think it is just water in the fuel or something?
3500 Chevy truck repair part 1
My friend is getting ready to buy this truck and we wanted to know if it
runs, we ran into some problems...
1. fuel was watered down due to storms during the last months.

it will pull through though running strong, in other words, it is a

GM Troubleshooting Part 5 - Fuel System including filter, pump, injector, regulator
This is part 5 of a multi part video series about how to troubleshoot any
ignition, fuel injection or timing issue. I describe the fuel system and
what I did to test it. specs referenced in the video: fuel pressure (in
PSI): TBI (9-13), MFI (41-47), CMFI (58-64), CSEFI (55-61). Those
pressures are for key on, not running. When running normal range is
3-10psi less for all injection systems. Injector resistance (in ohms): TBI
1.16-1.36, MFI (11.6-12.4), CMFI (1.37-1.77). In the video I forgot to
mention it is fairly difficult to bend the spider legs of the new injector
unit so they fit in the intake holes. Pay attention to the way the
original was installed (legs going over/under the nut kit lines) and try to
replicate the original routing. Oh... and I forgot to mention that if you
have a fuel lean condition, spray quick start in the throttle body and see
if it starts... if it runs on quick start, you have proven your condition
is a lack of fuel.
UPDATE Dec 8_2011: I still have the 2 moulded fuel injector lines (new
never used) and I want to sell them... if you need these lines send me a
private message and we can work out a deal. Thanks.
4.3 TBI running poorly
wtf is wrong with this?? Sometimes runs decent, sometimes runs like crap,
never runs 100%. Check engine light 'doesnt work'. (yes the circuit is
fine, the ECM just never turns it on, even with key on/eng off) Bad ECM??
