Sounds like you have hit all the bases except fuel. Inexpensive fuel test gauge hook up and turn key to on should read at least 60 PSI. Crank engine and see it pressure goes down bad fuel pump or regulator if doesn't hold over 55 PSI

Fuel pump is new and i got pressure

Check your icm module that connects to the pick up coil under the distributor coil

Check your position of your cap it could be timing

Did the truck run before you changed the timing chain if yes you may have to revisit that repair as all your issues seem to have started after that, if no than you have to start still have to re-check spark and distributor timming.

I have rechecked everything 4,5,6 times over on my dash the security light on the dash is on and stays on never goes out.

Bet it had to do with your keyfob or security chip/dead battery possibly.

Power loss

Chevrolet Blazer 1995  198 miles
Hi everyone, I have a van blazer 95 vortek 4.3 v6 ls and it was having an oil leakage through the crankcase gasket. When taking it to the mechanic, not only the crankcase gasket but also the filter and oil were changed. After that, the vehicle started feeling weaker than before and even once stalled on a parking ramp. A buzzing sound could be heard as if the gearbox was out of oil. What might be happening? In case it has something to do, I share that before the tuning of the car, only the change from first to second gear could be felt as the car jerked a bit. Luckily now this problem is not there any more. Has this ever happened to you? What might have been?

I tell you buddy that, when removing the carter and filter, you can check whether there is a transmission damage, either because the oil contains waste or little metal pieces or because the filter faulty. You should have started by scanning the vehicle.

Thank you Becca for your comment. I was thinking that may be the mechanic touched something else than only the crankcase gasket because I noticed him in a different car location than the one this car part is installed. It might be that he damaged the gearbox a bit in order to charge me even more.

Stalling issues

Chevrolet Blazer 1993 K blazer 275365 miles
I have 1993 K Blazer that seems to stall when its hot and humid out... I have put new motor that now has about 60,000 miles on it... I have replaced map,sensor,egr,distributor,plugs,wires,coil,vacuum lines,fuel pump, fuel tank because it had a hole, vents in tank, fuel filter and many other parts and noone can still seem to figure out why i have intermittent stalls... It could be on interstate, at red light, stop sign it just will stall and start back up... It always seems to do it when it is hot and humid or just started because i didnt have this problem over winter or spring... Can someone please help me

Parasitic draw from battery

Chevrolet Blazer 1999 Lt 200000 miles
It starts and runs from a few seconds to a minute then stalls the idler pulley is bad and makes us think it’s causing the alternator to not charge properly. It also sat for a good while before my cousin got it so I’m thinking the fuel pump isn’t putting out the right psi. It also starts to struggle when it’s in any drive gear. We’ve taken the starter off and cleaned it thoroughly, replaced alternator and battery and it ran good for a while it’s got engine noise I’m guessing could be a spun bearing because he’s ran out of coolant twice and his oil pressure drops at the same time. Could mainly use help narrowing it down.

There are several potential issues that could be causing the problems you've described with your Chevrolet Blazer. Here are a few possibilities:

Fuel pump: If the fuel pump isn't putting out the right pressure, it could cause the engine to run poorly or stall.
Idler pulley: If the idler pulley is faulty, it could cause issues with the alternator and result in a parasitic draw on the battery.
Spun bearing: If there is a problem with a bearing in the engine, it could cause noise and potentially cause the engine to run poorly or stall.
Alternator: If the alternator is not charging the battery properly, it could cause a parasitic draw on the battery and result in the vehicle stalling.
Battery: If the battery is not holding a charge, it could cause the vehicle to start and run poorly or stall.

Oil pressure drop down

Chevrolet Blazer 2005  110000 miles
When the engine's temperature is around 100, which is its normal range, and the car is stopped, the engine's pressure drops down. I might be driving for miles without any problems but, when I stop, it drops. I've changed the filter, oil and even gave it Flush.

It might be that the acceleration is low and that is why it tends to stall. It might as well be the oil sensor or more probably the oil pump.

The same happened to my Blazer 98 and what I did was to move the acceleration, approximately 1/4 of a turn in the throttle body and the problem was solved.

Front end noise

Chevrolet Blazer 2002 4Dr, v8, 4x4 152000 miles
I too have a clunk in my passenger side front wheel,but my concern is a vibration that comes and goes while driving. Sounds almost like you are foiling over a grated road. Suggestions?

Electrical failure

Chevrolet Blazer 2001  250000 miles
Good afternoon, I would be glad if anyone could help me with my problem. My car had a failure in the fuel pump's fuse, and at the whole fuse box was replaced by a new one. That was the moment when a strange electrical failure appeared. I've already bought three batteries and a whole fuel pump and the problem is still there. It has happened only once that it started and lasted on for an hour and then stalled. I've also changed the coil and the module but it is still failing.

Chevrolet Blazer 2000 4x4, manuel 215000 miles
For two week's prior to incident when i shut off the truck i could hear a boiling like sound coming from the coolant resivoir. Radiator was full. But i have never heard this sound before and ive been under the hood for last couple years banging on the fuse box when it wouldnt start. To the current problem... The battery light came on, then it started losing power and shut off. It wouldnt start after that and has been in an auto cocoon ever since. It had light's, and spark. But no sound when turned over.
