Question type: Maintenance & Repair

Can i get some help please I need a
mechanic who can tell me why my 2002
Gmc Sierra 4.3 aint getting no spark
anywhere and I followed everything on you
tube and nothing! I've changed plugs,wires,
new coil, new rotor, new distributor, checked
timing, changed crankshaft sensor,
camshaft sensor, checked all fuses and
relays, its got all new sensors 02, map, mas,
and temp sensor, new fuel pump, fuel filter
and put in a new computer and still nothing!
Used the obd tester and reads no codes
WTH! I give up! I should have taking it to the
shop to begin with probably would have
been cheaper than what Ive already spent.
So thats my story lol and I need help
pleeeeeze! Mahalo
