When it stops running have checked to see if there is spark at the spark plugs ? Does it have fuel pressure ? Does the check engine light come on ? You could have one of any number of thing's wrong ! Just with the ignition system alone you have ?€¢ Vehicle control module (VCM) ?€¢ Distributor ?€¢ Ignition coil driver module ?€¢ Ignition coil ?€¢ Crankshaft position (CKP) sensor

Welcome to FixYa.com,
Have you checked the fuse ?
Take a 12 volt test light and check each side of the fuse no light to one side could mean the fuse is blow, Regards, Lee

The timing marks, when aligned is when the #1 piston is on top dead center. They are on the harmonic balancer and the tab is bolted or welded to the timing cover.

Have someone check the connections from the harness connector to the wiper control board to see if the solder joints have deteriorated. Might need to be re-soldered.

Not without alot of work converting one to the other. The wiring would be different, the engine computer, the exhaust, cooling, and so on.

some thing to think about both have different types of computer coding, wiring harness, are the motor mounts in the same place, is 1 a stick shift, or automatic, are you using the motor the motor with the original transmission for that motor, or our you switching just motors if so than you will need a converter for the transmission, is emissions the same for each model (I DONT THINK SO) EMISSION are set up differently, the linkages for each vehicle may be different, smog setup will different depending on the year it was made. will the rear ends line up, is the drive train, or drive line the same or different, wheel base the same, will your new frame support the motor weight. will the header rub on the finder wells, after install the new motor will you be able close the hood, the air clean will not allow you to close the hood. will the stir wheel line up. brake lines in the same location, all the fluid contains in the same location and will the new body configure for the motor mounting and alignment of all the equipment the old car had or did not have. just some thing to consider before doing this project.

Hi! First of all, HC (Hydrocarbon) are the residue of petroleum based product combustion. If your HC reading are higher than the OBD2 legal limit (220 ppm), the most common causes could be a leaking fuel injector, abnormal oil consumption, a faulty Oxygen sensor or worn out spark plug / distributor cap / spark plug wire. To be honest, I would need more accurate details such as NOx ppm, CO ppm, CO2 ppm and Oxygen ppm and if there is any repair that have been made on the car recently to give a proper diagnostic. Warm regards

Unplug the power to the abs pump. Under the master cylinder

means misfire in #5 cylinder. found this for you. hope this helps
Common Problems That Trigger the P0305

• Worn out spark plugs, ignition wires, coil(s), distributor cap and rotor (when applicable)
• Incorrect ignition timing
• Vacuum leak(s)
• Low or weak fuel pressure
• Improperly functioning EGR system
• Defective Mass Air Flow Sensor
• Defective Crankshaft and/or Camshaft Sensor
• Defective Throttle Position Sensor
• Mechanical engine problems (i.e.-low compression, leaking head gasket(s), or valve problems

Common Misdiagnoses

• Fuel Injectors
• Oxygen Sensor(s)
• Power Train/Drive Train problem

ok if the truck went through water some water may have got on the distributor wires i dont think its a fuel pump problem but if you could check to see if its firing at the spark plugs the check the fuel pressure and if you have some wd/40 spray the spark plug wires and the distributor cap and try starting the truck

You will need a ball joint removal kit that can be borrowed from an Oreilly part store. It looks like a tuning fork. Take of the wheel. Remove the nut holding the ball joint in place and then put on the removal tool...probably the medium one. Using a hammer hit the end of the removal tool forcing the wedge in between the arm and the ball joint until it pops. Do not be afraid to swear and hit it as hard as you can.

Water in the oil is sign that head gasket has blown or head or block has cracked. Either way, very bad indeed. Engine will need major repairs or replacement.

Hello Donald! First of all, a lot of misfire condition are not directly linked to the ignition system of the vehicle. For instance a lazy O2 sensor (B1S1) or one with a burnt out heating element can cause the issue. One thing that is easy to check that can cause misfires is a defective EGR valve. You can remove it from the car and inspect that it closes nice and tight by pouring some fluid on the intake part of the EGR valve and see if the other side gets wet. Alternatively, you can inspect it on the vehicle. Simply start the car when the engine block is cold, let it idle and then put your finger on the base or intake side of the EGR valve and wait 2-3 minutes. If it become so hot you cannot touch it with your fingers in that 2 minute delay, it needs to be replaced. What happen is that when the EGR valve stays partly open (stuck open or simply defective), part of the exhaust gas, which are burning hot, get sucked in by the vacuum from the air intake and passes through the EGR valve and heat it up fast. A proper operating valve will not open until the engine reaches a certain temperature (usually around 80°C)and when the car is being driven, both condition only meet way after 2 minutes. If I remember right, the truck you possess (a 2 wheel drive I presume) has a 4.3L GM engine with a Vortec intake system. If so, the EGR valve should be right in front of the engine, behind the radiator fan and near the intake manifold. Also, be sure to place back the EGR valve in the same direction than it was, rotating it 180° will cause the valve to be stuck open by the engine's vacuum and WILL cause misfires. and rough idle. I've attached a picture of what it should look like on your truck. The arrow is pointing the front of your car by the way If it did solve your problem, please consider giving me some credit, doing so will help me progress in rank and providing more solutions on Fixya Warm regards!

Will the motor turn over?

Pretty sure it is a 10amp fuse for inflatable restraint control module

Check the batteries. If remote is the one that came with it. could be wore out.

Search google for a u/n and p/w to a site called ebsco.com. They have all the service manuals for vehicles, you can look up the removal procedure there.
