You might want to ck your fuel injectors.If you have an 6 cylinder vortec,it could be one unit underneath the intake manifold.If you have a 4 cylinder they could be 4 seperate units.Good luck.

OK everyone! I went and rented a fuel pressure gauge. 0 pounds. pump was still cycling checked connections for full power all good. Direct connected fuel pump to battery, and it sounded good. Submerged in bucket of water,and reconected to battery, water pumping out top of pump(plastic housing) not fuel line.I dont know if that is all my problems, but I think I would bet that it is. I ordered a new pump,so as soon as I get it in I will repost this, and I hope it might help some of you. Till then good luck.

#292 of 319 1994 GMC SONOMA- starting problems.
Mar 27, 2012 (2:21 pm)
Hey guys, I'm a girl so forgive me if I sound dumb. I own a 1994 GMC Sonoma. It's the V6 4.3L TBI Automatic. I am having problems getting it started. Occasionally it starts just fine, but other times it will crank over, but will not fire. The fuel pump primes every time, no exceptions. I have brand new air filter, fuel filter, new plugs, new wires, new ignition switch, new oil, new oil pressure switch, new oil sending unit, and some other new things. I don't know what else could be wrong with it. Someone told me it's got to be in the ignition itself, such as something along the lines of the coils.
I'm also having a bit of electrical problems. The switch for my turn signals/lights will not move back and forth to turn my brights on and off, and the the light for the brights, as well as both of the arrows stay lit up on the dash while I have my lights on at night. Someone help me, I love my truck, she's a good girl.... but I need to fix her before she goes bad totally. HELP!

Try a squirt of starter fluid NOT MUCH and see if it starts if so may be an injector problem. As for the dimmer turn signal switch it needs replacing not an easy job you'll have to pull the steering wheel switch is about $50.

I agree with Mr Green's suggestion with the starter fluid. Looks like you've put a lot of time and money into it. I guess you inspected the cap and rotor. The carbon electrode in the cap sometimes wear out or come loose and fall out. The turn signal/ dimmer switch on the earlier s10 have always been a sore spot.

When you say it won't turn over do you mean it is locked up or it won't start?
#298 of 319 98 S10 starting problems SOLVED!!!!!
Jun 09, 2012 (7:32 am)
Ok, after reading thru all these post, None helped solve my starting problems. BUT I did find out why my 98 S10 wouldnt start... Apparently when you drive a 5 speed, and have big feet, sometimes you can "grab" wires with the top of your foot, effectively pushing and pulling wires that are near your clutch and brake pedals... After removing the under dash panel, i adjusted some wires, got back into the seat and it started right up first try...
So I hope that this might help someone who is having problems with their Manual tranny starting.
My symptoms were:
Key in ignition (Beeps and Fuel pump engaging)
Press Clutch then turn ignition
Dash/Radio/Lights all went dead (ALL power lost)
Release Clutch and Ignition, ALL power came back to previous items.
Push sit back as far as it will go (Im a big guy)
Remove under dash panel (2 short screws for Modular hookup, and 2 long screws holding the panel in place)
Lay inside the best you can, need both hands free.
Look around and look for wires that are hanging or near the clutch/brake pedals.
If any wires, secure them away from pedals with electrical tape/zip ties/etc.... (Up is always the best policy here)
Once you have done that, try to start your S10! It should start if you got all the proper wires moved and secured.
After you have it fixed, simply put everything back the way you pulled it apart!
7mm socket w/ ratchet (7mm Nutdriver will do also)
Electrical Tape/Zip ties/etc...
And 30 minutes of your time.
I really hope this helps someone out! I missed a day of work because this stupid S10
