SOURCE: vacuum line for fuel pressure regulator 98 Tahoe

Was there a hose on the old one? If not, you don't have one. It is most likely your fuel pump if you are not getting fuel.

SOURCE: no power to fuel pump and the ecmb fuse bows as soon as i put it

Unplug all wires to the distributor, coil, fuel pum and injectors, then see if the fuse blows, if it does, sounds like an ECM failure.

SOURCE: ecm 1 fuse blow when attemping to start vehicle

So as I understand it the fuse only blew after a fuel pump job.

There is a TSB on repeated fuel pump failures with these trucks. The fix is to also replace the harness connector that plugs into the tank harness.

Unplg the harness and inspect it before you turn the key again if you suspect this.

03 tahoe pcm 1 fuse keeps blowing after electrical surge while driving

bogus post, fuse told ,is not correct name and now told not it is not blowing,(ouch)
5.3L V8 , now told, ( this fact puts you into the right chapter of the service manual for sure electrics..)
bogus post#2, fuse PCM-B are not blowing but why are you talking about it at all.?? sure other posts else where? guessing?

stop listening to other guessing what is wrong,
all we know is 12vdc power surge, of some kind,
if you looked at the drawings the things that can fail here are huge(vast). I invite you to read the service manual.
yes fuel pumps do short, want to see a pro Duane on youtube , and his scope showing bad commutator segments of a fuel pump?
huge current spikes, sure but that is a guess. (the video is how to find things going bad before they hard fail dead)

so not told , is engine still dead, ? cranks but does not start, , and did you know dead is the most easy failure of all
to find, safe and sound, not moving and dead is easy to test. (like no spark or fuel pressure dead,etc)
hard jobs are failing moving
or is intermittent.
or only in 3 gear
or only up hill.
or only in left turns. (add endless list here) but the point is made.

dead is bliss in my book , and simple tests find out why.
no voltmeter
no scan tool?(real)
no tools at all?

Where can I find the inertia switch on my 98 Chevy Tahoe?

There is no inertia switch used on GM vehicles ! No power to the fuel pump ? Check the fuel pump relay in the under hood fuse / relay box. GM Fuel Pump Relay Testing

Why wont my 98 chevy tahoe start

Either it is not getting fuel into the cylinders OR the spark plugs are not firing. Could be defective ignition switch, blown fuse to the fuel pump, blown fuse to the ignition, bad connection somewhere, you failed to pay for your permit to drive from the Homeland Security Bureau

98 tahoe put in rebuilt trans. now no fire to fuel pump wont start blowing fuses

Depending on which fuses are blowing, you may have shorted a wire in the harness to the fuel tank.

98 tahoe put in rebuilt trans. now wont start or even crank

Adjust the gear shift cable so that the park position sensor will move to the right position then it will crank. Right now it thinks it is engaged in some gear.

Why won't my 98 tahoe start after it was sitting for a year? i bought a new battery so that is not it.

Did you put stablizer in the gas before storing it? Does the fuel pump run for 2 seconds when the ign is turned ? Have you checked the air cleaner for debris? Do you have spark? You must have air/fuel/spark to start.

Fuel pump fuse blows quick

You have a short between the fuse and the reset valve . you have to trace the wires in between the fuse box and the fuel reset valve to see if they are pinched and a short is occuring.Follow the wiring from the fuse towards the back .
