If a vacuum leak occurred right after the carburetor was replaced then the gasket underneath it was not installed properly, is missing, or the vacuum hoses were not installed correctly. Prior to removing the carburetor I would double check the...
Hello there, thank you for asking about your 1992 Isuzu Pickup. A professional will have the correct equipment to read OBD1 codes. Retrieving the diagnostic trouble code(s) is the first place to start when diagnosing your vehicle. Increasing RPMs changes...
Hello there, thank you for asking about your 1994 Isuzu Pickup. For your vehicle, minimum compression is 114 PSI and all cylinders should read within 70% of each other. So, according to your results, compression is good. My guess is...
This sounds like it could possibly be a fuel-related problem for your 1991 Nissan Pickup. I would want to know what the fuel pressure is by testing with a gauge. I also recommend doing a compression test to verify good...
Toyota (https://www.yourmechanic.com/scheduled-maintenance/toyota-tacoma/) is the most dependable. I remember seeing a '99 Tacoma with a 4-cylinder engine and standard transmission. It had 800,000 miles on it and it was still running pretty good. They make solid trucks. There is no arguing...
Hello. If it starts and runs fine when you adjust the timing and then turns off right after you accelerate then the timing may be changing right then. It may be a distributor problem, or more commonly, a failing timing...
Hi. Noisy lifters can occur for a number of different reasons. The most common being low or old oil or a poor quality oil filter. If the oil filter is restricted or if it is full of debris, then the...
It sounds like the throttle cable has broke and needs to be replaced. I would have a certified technician come out and see if they can get it back on or, if it is in fact broken, have the throttle...
If the lights are fully illuminated, the starter or it's circuit is the most likely cause of your problem. However, an internal engine problem or problems with the battery could also be the cause. A trained technician will be able...
I am not surprised to hear that your Nissan struggles trying to move a heavy load up hill!! After all those years and miles, I would be glad that it still ran and save it for lighter work! Old trucks...
Hello there, thank you for asking about your 1993 Isuzu Pickup. It sounds like a bad ground in the instrument panel circuit. Looking at the wiring diagram, I see the AC heater control panel and instrument cluster share the same...
Hello there, thank you for asking about your 1995 Isuzu Pickup. You said you hear it trying to start, which means to me that it is cranking but not starting. If the engine cranks normally but doesn't start, the cause...
Code P0722 is an output shaft sensor code for the transmission. While that may be an indication of an issue, it would not cause the truck to just quit. A catastrophic failure of the fuel pump, ignition system, or engine...
The cooling system would need to be opened to see if, when the engine is cranked, the combustion of the engine is pressurizing the cooling system, and blowing off the hose. The head gasket may be blown. I recommend having...
The motor is probably shot. It sounds as though the head gasket is blown, allowing coolant into the engine; when that happens, all you can do is replace the engine or rebuild it. I would recommend taking it to a...
Hello. If the engine will only run for a short period of time then it may have a failing fuel pump or an electrical issue. Being that you stripped out the fuel filter connections, the metal lines may need to...
It is very possible that you have a weak fuel pump. Having to keep your foot on the accelerator to keep the engine running is an indication of low fuel pressure. The pump works harder at higher RPMs in order...
