Engine has not been running. Not firing.Changed heat sink, coil, ignition module, distributor assembly including pickup coil, and camshaft counter sensor. Thought that computer could be the problem until I found this leah. Maybe there is something internal that is keeping it from starting.Don't know.
With replacing all those parts an not fixing the thing ,your best bet , take it to a qualified repair shop. Some place that test's an not guesses .
SOURCE: 2001 GMC Sonoma Engine stopped while driving
sounds like it could be plugged injectors or a timing problem.
SOURCE: engine won't start
when you pulled the dist did you mark it before pulling it and were ALL the timing marks lined up
if not you will need to pull # 1 sparkplug and get the piston up to TDC (top dead center) on the compression stroke then put the dist back in with the rotor pointing to # 1 plug wire .
Be sure to check dist direction of rotation and comfirm firing order
SOURCE: My GMC pickup will only start with starting fluid.
Check your fuel pressure at the shredder valve, there should be 60 to 65 psi when the fuel system is primed. "engine not running" once the engine is started the fuel pressure should drop around 5 psi, any other readings will give you a no start or no run. Your fuel filter may be close to the end of it's life or the fuel pump may not be pushing enough pressure when the battery is under load and under 12 volts, once the engine start's the voltage rises to 13.5 volts giving the fuel pump that extra to keep the fuel pressure up. The other common problem to your Vortec engine is the fuel system. The fuel pressure regulator is know to go bad on the Spider system, which also would give you the no start problem. Start simple with replacing the fuel filter and check the fuel pressure at the shredder valve and then go from there. Keep me posted, be glad to help you get your truck running 100% again.

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.
i have a 1992 gmc sonoma with a 2.8liter engine with a 5speed manual trans. does it uses atf or gear oil if it uses atf what kind?
