Check that the Park/Neutral switch signal is seen by the ECM. (Watch Diacom dispay while you shift.) This is a load signal that tells the ECM to increase IAC counts when in gear. The other load signal is the A/C switch (or A/C clutch).

Unplug the relay and check for power at the terminal fed with a large red wire. If no power, look for a blown 'fuse link' at the back of the alternator or at the junction block (mounted at the center of firewall). Test by trying to stretch the fuse link wire... a bad fuse link can have a...

First, make sure you don't have a cracked or loose exhaust manifold. A small leak will make a popping noise that sounds like a lifter tap. Next, try to identify the rate (crankshaft or camshaft speed) of the 'tap' noise. Connect a timing light to any spark plug cable. Run the engine at...

Ripped from the 'book'. (Typhon Service Manual Supplement - still available from Helm, Inc. @ $60 - http://www.helminc.com/ To find the specific manual, enter the 'year', 'model' = Typhoon or Syclone, ... for 'document type' leave it at 'All Types'.) CODE 45 - OXYGEN (O2) SENSOR CIRCUIT...

Re: idle screw Re: idle screw When looking at the throttle body from the front of the engine, the stop screw will be situated horizontally inside the casting boss just above the throttle shaft. The 'stop' end can be seen on the left between the casting and the throttle bracket stop tab. The...

You should check the P/N switch input to the ECM. The computer adjusts IAC counts and Air/Fuel ratios based on this transmission 'load' signal. A 'scan' tool or DM software should show an On/Off signal change as you shift from P to R to N to D.

Re: Junk ECM????????? What sort of exhaust repair? Was arc welding done to the exhaust while on the truck and without disconnecting the battery and ECM? This 'bad practice' can easily damage electonic systems and may have 'cooked' the knock sensor, ESC module, or ECM. Whenever you notice a...

Not your fault. Murphy's Law states that "a round plug will always fit into a square hole". Another Murphy's Law to look out for when working on your car or truck: "When a part is accidently dropped, it will land in such a way as to do the most damage". And a Corollary to this: "The amount of...

Before you do all that, carefully check the oil pressure sending unit located above the bellhousing (next to distributor). This sender can leak and gravity can make it look like a rear main leaking problem.

If you can find/borrow a factory Syclone/Typhoon shop manual supplement (or a CD manual?), the ECM pinouts are provided as follows: In the 1993 Manual Supplement, pages 3A-86 to 3A-90 cover the complete ECM circuits and pinouts. In the 1992 Manual, the same pages are 6E3-A-3 to 6E3-A-7. I do...

Re: won't start, no trouble codes Your ECM appears to be 'dead'. The 'Check Engine' light should be 'ON' steady when the key is 'ON'... not just flash briefly. This light will only go out when the ECM receives reference pulses from the distributor (engine running) and there are no codes set...

You also need to think 'crash' survival. Nothing like being knocked unconscious or trapped in your truck as it bursts into flames because that soft aluminum fuel line split open on impact.

For those that were/are still interested. I found this kit at my local transmission rebuilder shop for about $4.00. It was hard to find listed on the internet because it doesn't have a consistant name. Every shop seems call it something different. Continued searching finally turned one up...

Cheapest quick fix: This TV cable spring kit will allow you to set the cable one 'click' tighter than OEM. This will raise TV pressure slightly to give you a firmer shift. It may also extend the tranny life since less slipage will occur during shifts.

(This is assuming that the solenoid plunger return spring is there and in good shape.) First, remove the 'purple' wire only from the solenoid. Then activate the starter using a remote switch (or your screwdriver). If it still doesn't stop cranking, replace the complete starter. The last time...
