Maybe you unknowingly dropped a small nut or bolt down an intake port while the engine was apart or maybe a couple fuel injector lines from the spider got crossed during the process.
In back of engine, it can be reached from the top.
Assuming this is the 4.3L engine, one.
You have another problem other then the knock sensor if the engine will not start and run. A knock sensor will not cause the engine not to run.
left side back of engine by dist.
engine misfire. i have a '96 Chevy blazer but i don't have that problem, i was reading reviews on the car and found out that some of them do that.
there may be two knock sensors on that 4.3L engine. One would be on the back of the passenger side cylinder head and the other would be on the drivers side, lower engine block area.
I have a 92 s10 blazer and my code 43 was fixed by replacing the knock sensor. so maybe check the knock sensor and the wiring from that to the ECM.
the knock sensor cuts the engine out so it won't damage the car if not replaced, the car just won't work.
Yes. A fuel pressure regulator maintains the adequate fuel pressure required by the engine. A faulty fuel pressure regulator might leak fuel or cause your engine to run lean. It could create hard starts, knock and ping, or hesitationat full throttle.
YES, It sure can if that is the problem. FIRST you need to have the engine scanned with a OBDII engine scanner to see what CODES the computer has stored.
It is screwed into the passenger side of the engine block just in front of the starter.
The knock sensor just advances and retards the engine timing only. If there is a noise in the engine then you have engine are valve train problems. The knock sensor will not make the engine knock.
