Question about 1996 GMC Sonoma

1 Answer

My '94 Gmc Sonoma engine won't turn over when trying to start - Do this means my engine has lock up ?

Just recently found my biggest problem with my truck - replacing the Distributor.( instantly starts up), but now I have another problem it won't start and my engine won't turn over. This problem came about after I replaced the Fuel Injectors which had going bad...gas did go into carburator area as I tried to start the truck. How can I fix this problem and get my truck back on the road ?

    either you move your timing OR cross your wires COUSE when you move your intake to replace your injectors , a bracket is some how mounted to the intake, and the timing was probably moved [ just guessing maybe , it could be, ]

SOURCE: 93 gmc sierra 5.7 liter engine, injection carb,

you say you replaced the fuse, but does the fuse have power? the gray wire at pump should have power when cranking, or for 2 seconds when turning key on. At fuel pump relay, put power onto gray wire, the pump should run if the wiring is good. if it doenst run then ck for power at fuse while power is on gray wire.

Sounds like you have several problems.
If the engine will not crank, do you have power on the purple wire on the small starter terminal when the key switch is in the start position ?

1997 GMC Sonoma, will not start.


check your battery posts and terminals are clean, if is ok, you can check the wiring the charing circuit, maybe the guy installing the stereo broke a corroded wire off.

I have a 1995 GMC Sonoma that will not start when turn ignition switch lights will come on etc but engine will not turn over battery is good etc but nothing happens


Make sure all the ends on your battery cables are clean and tight. I got a tow in because my car would not try to start even tried boosting to no avail. All my lights and radio was working but they said the cable was corroded and would not let the full power work. We replaced the battery cables and worked like new now.

1996 gmc sonoma


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} Long start time and misfires can be caused by retarded engine time. Purchase a timing light and check your engine time against the front pulley and the timing scale located around your timing chain cover. If you have recently had your timing belt or chain replaced you could be a tooth off.
With regard to your ABS light the easiest thing to check or replace is the speed sensor on the wheel. Because this is a magnetic pick-up sensor and due to the location (on the wheel behind the rotor) can be susceptible to corrosion. That is also the most common cause of an illuminated ABS light. Do you have 4 or 2 wheel anti lock? The 4 wheel abs doesn't change what could be wrong, it just means you have more speed sensors to check.
