Installed a starter on my 1994 chevy suburban, accidently pinched the starter wire between the starter and block now I don't have power to the starter or dash lights, fuses checked good wire is fi

Ignition switch possible or a main fusible link. go to http://www.bbbind.com/free_tsb.html free wiring diagrams .Enter your vehicle info . year , make , model an engine . then under system click on electrical distribution . subsystem -power distribution . Click on the search button ,then the blue link . Check out the wiring diagrams .You'll need to do some voltage testing to find if voltage is missing . This vehicle has eight fusible links ,one feeds the ignition switch . On the fire wall there should be a junction block where all these fusible links are connected to a main wire from the battery . You can try to see if one is burnt by pulling on them , you will feel the insulation stretch if burnt inside .

In most cars & truck with this problem, the most common reason is a defective alternator.
In the meantime, unhook that battery each time you stop the truck to prevent dead batteries.

its maybe the starter...fried to

Disconnect the line somewhere and point it into a container, and power up the fuel pump with a jumper wire at the fuel pump relay. Put battery voltage to the fuel pump wire terminal where the relay plugs in. Careful you don't get the wrong terminal, or you could fry your computer! And for gosh sakes, be safety conscious. Fuel lines are under pressure, so relieve the pressure before you take a line loose.
Another way is to raise the car on blocks or jackstands, and take the filler hose off. Then you can put a siphon hose into the tank and drain it.
A friend of mine wanted 5 gallons out of his Suburban's tank. He disabled the ignition, and used the starter cranking to make the pump run. He told me he got about 2 gallons before the starter got too hot and burned up on him.

The starter is next to the side of the lower engine block where the engine and trans meet(I believe on the passenger side on GM V8s)You should get 12 volts on the small(purple?) wire of the solenoid when the key is turned to "start".If you don't get 12 volts when the key is turned,it could be the switch on the shifter(usually referred to as the PRNDL switch)IF you get 12 volts at the solenoid when you turn the key,replace the starter(my Chevy work truck has gone through 6 starters(ONE A YEAR)since I've had it!)

1994 Chevy suburban during these years the alarm was after market , your best option is to remove the alarm,it installed under the dash at the steering column,the only wire they used was starter wire at the ignition with a relay connected to the transponder,there is a way around look for a small push button and press it hold it and crank the engine this bypass is hidden under the dash and can be in varies places

You have to count the number of flashes then check the repair book to see what it means. The sequence will continue to repeat, so don't worry if you don't get it the first time.

Put an injector noid light at the injector plug terminals to see if your getting a signal from the PCM(computer).If not try to find a computer from the same vehicle that works and swap it into yours to check.A PCM swap will take about 15minutes.

the fuel pump positive wire must have been cut in the accident and is shorted to sheet metal in the wire harness, look around the area's of damage for a damaged wirng harness.
