SOURCE: PCM module, ECM module 1996 Chevy Suburban K model

Powertrain Control Module = under right side of dash, near blower motor.
Engine Control Module = same as above
Vehicle Control Module = same as above

All Suburban vehicles are equipped with only one of these choices. Good luck.

SOURCE: Where is the fuel regulator located on a 1988 tbi

No, low fuel pressure is caused by a weak fuel pump.
High fuel pressure is caused by a faulty fuel regulator.

1989 chevy 44 engine swap


for a swap like that a chilton book would cover info for both motors and they cost under 20 bucks. just saying it beats the hell out of guessing at it or taking some schmucks advise from the internet. since your old 5.7 had TBI im hoping the 454 your swapping it with is also a TBI, if not your best bet would probally be to convert to carb but your going to need to replace the fuel system as the 2 high pressure lines that ran the TBI wont work with a carb. if it is TBI your going to need the ECM that came with the 454 as the 350 one is just going to "get confused" and have issues. Since your rig has an older ECM you can remove the Electronic senders and replace them with manual ones to simplify everything ( i have an 89 chevy i built a rat 355 for so ive been through this before) . without knowing exactly the year of the 454 thats about all i can think of to watch out for on that swap, i hope your not trying to mate the 454 to a 4L60, your going to need at least a 4l80 with an upgraded sun shell gear or a heavy duty manual ( at least 10 spline and 12 inch clutch).

Have 1987 chevy pickup truck not getting fuel to the TBI unit. when you turn ignitionkey to "on" pump starts to pump fuel, and will start to run but shuts off after 2 to 3 second or so. Even...


Kent, That sounds like normal operation.....see this link (https://www.justanswer.com/chevy/0z9bu-fuel-pump-relay-located-1987-chevy-silverado.html) The ECM shuts the pump down if the engine doesn't begin running in two seconds. I would bleed out the fuel line up to the TBI...crack the line at the TBI then cycle the key a couple of times until you see gas coming out of the line at the TBI. That will ensure you have fuel at the TBI, then try to start the engine. See the link for additional info.

Remove the radio and make sure he did not cut any wires to the ECM engine control (module).The wires run along the back of the radio to behind the glove box to the ECM.If this is all good then check the connections.If all is good then you could have a bad ECM.Tyr the scan tool on another vehicle to make sure the scan tool is working properly.Hope this helps.Good luck.

Where is the fuel regulator located on a 1988 tbi


Sits inside the throttle body, you would have to open to install regulator. Also check your fuel filter make sure it's not clog, fuel filter is under truck on fram rail, while your there do a fuel pressure test, with a fuel pressure tester, should have 13psi.

No power up hills and pinging noises come from TBI little back fire.


Sounds like the knock sensor has failed. It's on the passenger side at the bottom of the engine block, in front of the starter. One wire going to it. Have you checked the timing lately, maybe it has moved?
