just looking for the location of fuel pump. 1/2 ton chevy truck 93 v-6 auto trans

my 92 s-10 blazer 4.3l throttle body has the check engine light on and the oil pressure guage is reading low (at the lowest point on the guage). the oil level is at the full mark on the dipstick. as i am driving and accelerating the pressure rises slightly and the light flickers on and off.(check engine light) there is no difference in the performance of the motor and the gas mileage seems to be the same. could this reading on the guage be a problem with the pump, oil sending unit, oil pressure switch and how can I properly diagnose the problem myself? and should the vehicle still be driven before diagnosis? thank you in advance for your response.

So i posted about a week ago.. but it happened again. It simply does not pay to replace the ignition module anymore.. it keeps on frying. What other possibilities could it be?

The ignition coils on the 2nd and 4th cylinder of a 2.2L 4I Ecotec engine are burning out, even with repeatedly replacing the ignition module. It has trouble starting up, and then when it does, the engine runs rough, very rough actually. It’ll only run a little over 25mph, and takes a little more than 5 seconds to shit out of 2nd gear (this is an automatic). What is wrong?

2005 chevy cobalt makes a click click click noise seconds after turning off the ignition

I have a problem with cold starts, there are no engine codes, have replaced the ETC sensor, cleaned the throttle body, and intake. replace the fuel filter. The only way to get it started is prime the throttle body with a small amount of fuel. it starts immediately, and then after when warm. When warm it will start without any problems. Only overnight or extended periods to cool down. then must prime again to start? Fuel pump or cold start injector?

The van just had a new starter and battery put in; the starter clicks when I turn the key sounds like its going to engage then when I try to turn the key again it doesn’t do anything what could be the problem?
