  • The purpose of an harmonic balancer is to absorb crankshaft vibrations. Harmonic balancers are typically constructed in three pieces. The first piece is often called a hub. It bolts to directly to the crankshaft. The hub is surrounded by rubber or fluid which dampens crankshaft vibrations. The outside layer is metal which has grooves on it for the belt. Over time the rubber and/or fluid layer deteriorate causing the outer pulley to shift forward. This causes belt miss alignment and can ultimately result in crankshaft failure. When the harmonic balancer is broken, it must be replaced. ATP Harmonic Balancers fit and function just like the original part restoring the engine to normal operation.

92 GMC 2500 no fuel

Showing 2 out of 2 Posts
Question From devildog4001 on 92 GMC 2500 no fuel

have a 1992 GMC Sierra 2500 4x4. It has the 5.7l/350 small block engine. The engine will turn over but will not start. At the moment it has no exhaust manifold and shoots very weak flames from the exhaust ports on the heads while it is attempting to start.

I have just replaced the heads on the truck with brand new heads. It has all new seals (head gasket, intake manifold, TBI, etc...) and all bolts were cranked down in the proper order to the proper torque. It has a new distributor cap and rotor and brand new plugs. I have checked the timing by lining the marks on the harmonic balancer with the timing marks and cyl 1 was at TDC. The rotor is pointed at the number 1 position with this configuration and I have attempted flipping it 180 degrees. I am getting fuel to the tbi and it is spraying from the jets just fine. The plugs are getting a spark (light and yellow but there).

When I remove the plugs and turn the engine I do not smell gas. When I unplug them and turn the engine they come out dry and I do not smell gas.

Response From Sidom Top Rated Answer

The 1st quick check I would suggest is to get a spark tester (not a old spark plug or screwdriver) and wind it out to 40kv. Then hook it to the coil wire and check your output, it should be able to jump that gap with no problems.

A weak coil will produce a spark in the open but won't be able to jump a plug gap under compression..........
