Hi Dustin, Any relationship to Hofman? Have the fuel filter replaced and the fuel pump pressure tested. If the catalytic converter becomes blocked it can also restrict engine performance, so much so it can stop the engine from starting. Regards John

Testimonial: "i replaced all that and had the pressure checked its all good. it starts up fine its just when im driving for a little bit and i go to press on the gas it starts to bog down but if i let off the gas it will stay running. so i restart it and then it lets me press on the gas and accelerate"

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

1997 Chevy Silverado will not start replaced fuel pump also replaced spider injectors. Call shut down while driving


Does the engine have spark to the spark plugs? Is there 12 volts to the coil and is the coil being triggered on the ground side? Check to see if the coil is sending spark to the distributor. Several more things to check that will not let the truck start. Check these and get back with me and I will help you more if needed. Good luck.

Hi,
Check the ignition distributor cap and clean the electric contact points it might be already dirty.

if one has a spark that means your ignition coil is still okay. Remove the whole cap and check the inside part and clean it, use emery board.
Check also the high tension wires( spark plug wires ).
Hope Fixya helps you!

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Since the engine cranks, the battery, starter motor/starter motor solenoid are most likely
good, so suspect everything else on the list. When you narrow it down, re-post with a
