HOW TO INSTALL SPARK PLUG WIRE HEAT SHIELDS 350 VORTEX HOW TO

Not checking all 4 spark plugs for spark and if all 4 spark plugs are bad, checked directly at the coil.(try to stay above 11v at all times, at the ECU)

Rotor installed in the wrong position of 3, USA rotors can not be done this way, unless you buy fleabay China knockoff noname JUNK.Top diagnostic error?, not checking Ignition timing for near TDC firing and missing the fact, that the cam timing belt has slipped!!!.Gross neglect of Distributor cap-rotor-wires-plugs ( called a tune up ).See cam spin? no? If not, you have discovered your problem. Timing belt slipped or snapped ( is cam spinning cranking? ) look down oil fill hole.Fuses must all be good, there are 3 fuses for ECU and COIL.( see fuse maps here) IG-coil, Dome, “FI”.Tools: a Timing light, if no timing light? your efforts are wasted, IMO! for Fouled but they should look GOOD.įail to look at the factory dash tachometer, and see that it moves to 400 rpm (or tad less) cranking, No? then Igniter is dead.įail to make sure you didn’t loose the Ignition suppressor module, no Tachometer cranking, and loss of injections as a result.įail to have ECU power, and grounds to ECU and distributor.

Pull the distributor, unless you learn how to re-time it from scratch.įail to see if the Cam is actually spinning! LOOK!įail to look for shorted spark plugs all 4 or 6 of them. Read the Haynes books, the data on distributor rotations is wrong.įorget you can check for spark with the timing light cranking, and see the cam has in fact slipped. (this combined information can save you lots of time)įail to discover the timing is way off and 100% proof the cam belt slipped. Spare design evolution is complex, over 5 generations of radical changes.įail to check spark at each spark-plug and at the coil. If spark is bad, all ECU’s Cut Fuel injection! This page attempts to cover 5 generations in 15 years span. STOP and do the ECU Diagnostic first, Please!

I try here, to cover all generations in the year range stated!. USA centric, other counties the ignition can be different!ġ989 to 1998 1.6L and up to 2005 on all 1.8L to 2.7L C.O.P coil based engine. You tested for spark first here using the tried and true way. See the CKP scope signals? and rules here? lots and lots of rules.See my simple bench test video of one type of CMP hall sensors.(can be done on car, unplugged & cranking the engine.).All 1.8L and up, CMP and CKP sensor facts.G16B, SOHC 16v OBD2 (added CKP sensor ) 1996 and newer.See the no start page for a fast spark audit. Installing a hotter heat range plug will reduce the pre-ignition safety margin, so it is better to correct the mechanical or tuning issue instead of changing the plug heat range.No spark? From 1989 to 2004 Suzuki Sidekicks, Trackers and Vitara’s Often hotter heat ranges have been used to address a fuel delivery or oil consumption problem. For a spark plug to function properly, it must have a tip temperature high enough to burn off carbon deposits (self-cleaning) and avoid fouling, while remaining low enough to avoid overheating the ceramic firing end and pre-ignition.įor most vehicles, the factory recommended heat range is sufficient however, on some modified or special-use engines, alternative heat ranges may be necessary. As a result, less heat stays in the ceramic firing end and more is dissipated to the engine. A colder heat range spark plug has an insulator design with a shorter heat flow path to the metal shell of the plug. As a result, more heat stays in the ceramic firing end and less is dissipated to the engine. The spark plug heat range only indicates the rate that the spark plug dissipates its firing end heat to the engine.Ī hotter heat range spark plug has an insulator design with a longer heat flow path to the metal shell of the plug. The spark plug is heated during combustion and must dissipate that heat to the cylinder head at a certain rate to avoid overheating the ceramic firing end. Another common misconception is that the spark plug is designed as a heat sink to “remove” heat from the combustion chamber. One misconception is that the heat range is related to the spark temperature or intensity. One of the most misunderstood aspects of spark plugs – is the heat range.
