It could be a number of issues. If your car started before you replaced these items, most likely one of your wires is in the wrong spot. If you were replacing in hopes to get your car to start it may be your starter. Know more about diagnostic @http://www.obd2express.co.uk

Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)

SOURCE: fuel pump relay hot

You could have a loose connection going to the relay. Loose or bad connections cause amperage to rise causing heat to rise. Check the plug holes where the relay pins plug in. Check for blackened metal or melting plastic around the pins. If so, check under the relay box for burnt wires, etc. and repair.

SOURCE: having problems with chevy s10 replaced fuel pump

Check the cable that goes from your battery to the fuse box the relay that is clicking is on. Check for lose bolts or corrosion of the contacts or something like that. If the relay is clicking it sounds to me like it is a voltage issue going to the relay.

92 s10 pickup 4.3 replaced the fuel pump, filter, relay, ignition control module, rebuilt the tbi system twice,and new plugs and wires it will crank over but won't start wat could be the cause of it


Did you troubleshoot before starting to replace everything? Was it really not getting fuel or spark? How about now, is it getting fuel and spark? How is the compression? Is the timing correct? You've stated everything you replaced, but have said nothing about what you've found while troubleshooting.

My 1993 s10 blazer is hard to start, cold starts runs for 15 seconds then dies and wont start after that! have fuel pressure and can hear pump run. good spark what could it be?


Check the fuel pump relay its inside the glove box the one on the left side of 3 relays . The fuel pump will still work on this vehicle ever if the relay is bad . The system is backed up by the oil pressure sending uint and that will supply power to the pump it just takes it some time for the engine to build up enogh oil pressure to trip the switch so it takes a long time to start and you may think of replaceing the unit as well that could be intermitant also check your fuel filter its under the drivers side door mounted to the frame
