1998 Chevrolet C1500 - Answered Questions & Fixed issues

Will it physically fit? yes. Will it be a direct replacement any everything hook right up and plug right in? If we are talking about an automatic then no. 1994's wiring was completely different than the 1997. Can it be made to work? possible, but I believe it would be more trouble trying to make it work than if the correct transmission were located and installed. If it is a cost issue where he has a good trans out of a 1994 he might see if a salvage yard will do some partial trading for the correct trans.

Check all connections and fuses/relays to see if you have a power liss . If possible check for power as close to the pump first .

A melted connector is a sign of current overload. Perform a current draw test on the motor.

I think you should buy repair manual first for your vehicle after that it will be easy for you to solve the problem. Check the link may be you will find something useful here Chevy Silverado Sierra 1998 2006 Workshop Service repair manual

top bolt if it's a stud and bushing type gets tightened until the threads run out - usually where the bushings squash pretty good. the nut on top will stop turning. Other fasteners tighten to about 50 lbs or so depending on the size of the bolt or nut. small bolts like 5/16, 3/8, 10mm shaft size get about 30 lbs. Torque is all about the size of the bolt ( the diameter) . Large fasteners like 1/2 in. and above get 50 to 80 lbs. . hope this was helpful

Don't worry about the torque specs .. Most mechanics would put a socket/wrench on and get them 'really tight'

Check the fluid level. How many miles on the truck?

Hi Dejuan, The link below is a youtube video on how to fix a car that idles poorly, Also there's moore video's down the right side showing the same thing, I hope this helps......CHEERS.. How To Fix Car That Idles Poorly

cracked o ring not pushed in all the way

You need a battery charger on this to do it. Put the key in and turn it on. Leave it on for ten minutes, turn it off for thirty seconds. Do this three times, then try to start the vehicle. If the battery goes low(below 5 volts) or you hit the starter. You have to start over. This is a relearn.

The first thing i would tey is changeing the fuel filter. Chevy has a problem with the design from the fuel pump to the fuel inlet on the intake manifold. What they did it is back up the power supply to the fuel pump from the fuel relay and split the curicut and ran the back up through the oil pressure sending unit . So even if the relay went bad while driveing the fuel pump would still get power and the truck wouldn't die on the road its a saftey thing .But if the relay is bad then the engine needs to build up enough oil pressure to trip the oil sending unit to send power to the pump from cranking thus a long cranking time when cold . Change the fuel filter first it should be replaced every 4 to 5 years anyway . A nd if that dosn't fix it try the relay it should be behind a panal inside the glove box on your truck and if that dosn't work replace the oil pressure sending unit. One of these 3 things should work if the fuel pump is working correctly

If you have a 4.3 L its in the back left of the distuburtor . You will need a special socket to remove it their 20 bucks or so . But the oil pressure sending units on these vehicles tend to have problems I have put in new ones that failed in a few days there just maid cheaply and it dosen't realy matter ware you get it dealer napa advanced auto .The socket is worth the money it will make life easyer

Driver rear exhaust manifold

first thing check all fuses, if ok your problem more likely rear tail lens circuit board where your bulbs push into. the sockets over heat and melt . this is a problem with these trucks from 1988 to 1999

Check for ground in the harness or add one directly to the radio

Damage wires,did you check gap,did switch wires?

you have a wiring issue there...check battery connections, connections at altenator, junction box and fuse pass through at the firewall. Make sure you follow your ground wires too should be one from the battery to block and frame to block

CK COMPRESION AND FOR SIGNAL A THE INJECTORS LIKE POWER AND GROUNG SIGNAL FROM PCM

If you haven't found the problem already. I suggest looking at the drivers side radiator tank they usually crank and seep slowly. If not leaking there, it's probably the intake gasket. Both of these problem are common to this make and model.

Make sure the injectors are metering. They are fired off of the pick up in the bottom of the distributor.
