first check the easy stuff. no air leaks around the air filter box and ducting going from there to the TB-throttle body.
then one needs to determine if there's spark or if there's a fuel delivery issue. IDK if this is coil atop plug config or not. but arcing a plug once remove to the block can determine spark. fuel delivery, though not difinative, can be checked by cracking a fitting after the fuel regulator, engine running. not diffinative becuase pressure is key as well. but if fuel seeps from the fitting, one *might* assume, for now anyway, that's good.
then one would check for valve function via the cam belt/chain(app). since there's no distributor, ome might see iffin the rockers/cam moves when turning engine. either remove a rocker/cam cover, or iffin your lucky, removing the oil filler cap, one might be able to see past the baffle, cam or rockers/followers are moving.
other than that, have the trouble codes retrieved. under a no start condition, the CEL/MIL lamp may not be a clue as the computer is typically is in test/self and systems wide, diagnostics mode at first turn key and is lit anyway.
if there's an issue with the fuel recovery/evap system, there will be a trouble code in memory.
best i can do fer ya.
Ah yes, the old "throw money at it until it's fixed" method. Perhaps you could describe this "problem" and if there are any computer codes associated with it.
Without knowing what your problem is, I'll guess that the blinker fluid is low.
You have to clarify what it's doing "the same problem" as you said and if there are any trouble codes on the dashboard.
It's a 2001 Sonoma, 4 cylinder. I replaced the fuel pump, fuel filter, ignition coils and wires, and also the spark plugs but so far I got the same problem. I was thinking it might have something to do with the charcoal canister or the purge valve. Any suggestions would be greatly appreciated!
