    truck cranks but won't start - Chevrolet Pickup

    Hi, my pickup cranks over but doesn't want to start. I tested my fuel pressure and found that it is low so I am thinking my fuel pump is bad but the truck will not start even if I give it a little starting fluid. I checked the 1 spark plug wire and I am getting spark there.

    Any other suggestions as to why it will not start or fire even with some starting fluid in it? Step 1 - Anytime you have a problem with electronically controlled components such as an engine, transmission, ABS brake, or SRS supplemental restraint system, Air Bag inspect all fuses using a test light and check the under hood power distribution center and under dash fuse panels. If all fuses test ok continue to the next step. Step 2 - To check for problems with electronically controlled components such as an engine, transmission, ABS brake, or SRS supplemental restraint system, Air Bag and the fuses test ok a trouble code scan is needed to identify any system trouble.

    Use a simple scanner tool to retrieve trouble codes and see if they relate to the specific problem, like a crank angle sensor failure code. If the trouble code present does not pertain to the immediate problem like an EVAP code ignore it until a later time, after the car is running.

    The reason we repair non-related codes after the engine is running is because sometime false codes can be triggered by the engine not running. Once the engine is running again the code present might cycle and turn itself off. You might say "if the engine doesn't run shouldn't it have a trouble code? If no trouble codes are present proceed to the next step. Step 3 - Determine if the engine has compression, this can be done a number of ways but the most complete method is to perform a compression check.

    Remove the spark plugs and perform a compression test on one cylinder. If one cylinder has compression then the remaining cylinders usually will be close to the same. Crank the engine over about 5 seconds, normal compression readings should be between psi and psi on each cylinder. If no or little compression exists additional tests will be needed.

    The most popular reason for an engine to lose compression is a timing belt or timing chain fails. If low or no compression exists remove the oil fill cap and observe camshaft rotation when the engine is cranked over. If no rotation exists the timing belt or chain has failed. If your engine has a timing belt and you cannot see the camshaft easily remove the upper bolts to the timing cover and gain visual access to the belt, recheck cam rotation by cranking the engine over.

    Sometimes a timing belt or chain can jump causing the camshaft to lose correlation with the crankshaft and therefore causing low compression. If the compression is ok proceed to next step. Step 4 - Test the ignition system output, ignition systems can vary in configuration but operate on the same principal.

    Ignition systems can consist of a coil, pick up coil, crank angle sensor, cam angle sensor, spark plugs, spark plug wires, distributor cap, ignition rotor and a distributor and any variations of these components. An ignition coil is a voltage stepper coil that transforms a low voltage 12 volts signal into tens of thousands of volts needed to jump the gap of the spark plug.
