I just bought a Syclone it has 41,000 miles on it but it has only had 265 miles put on it since 2001. The fuel pump was bad. I replaced it and it started up. The lifters are ticking and it's running ruffff. I am going to do a tune up this weekend and do a compression test. Can anyone tell me what I need to know about the problems I have described. Also is the turbo a Misubishi unit?

gas could be bad by now , and you need to hookup some sort of scantool to see what your motor is saying . Datamaster or TunerproRT are the top 2 favs around here .

The injectors have a notoriously loud tick. That could be the noise you're hearing. It's normal.

Like everyone else said possibly bad gas plus stock trucks have shitty idle from the factory :)
Also make sure you use a good fuel pump because stock hardly is enough fueling for the standard n/a 4.3 truck let alone ours

Also stock injectors tick like crazy so verify where the noise is coming from first before doing anything further.. also make sure you use the correct spark plugs which are AC Delco CR42TS or NGK UR5 gapped @.032 to .035. Get a good brass cap/rotor set and some decent 8 or 9 mm wires at least. Ignition can tend to be a bitch with these trucks.

Most importantly search this forum and read all you can before modifying anything.. it'll save you mucho head aches and if possibly get a scantool like www.ttspowersysems or tunercat to see what's really going on with the truck or find a local syty owner that has the scan software and see they can help you out.

Is your truck stock or does it have an aftermarket chip in it ?

Re: I need help with my Syclone

My question would be DID YOU CHANGE THE OIL. Even though you stated 2 hundred miles change it. Do a complete tune up change all the fluids possible then start troubleshooting issues.

After all the fluids are changed and a nice tune up with fresh gas take it for a ride to get the good gas flowing and drive it easy. I bet you a few days of driving it it will return back to life and run great. Of course i say this with confident that the truck was taken care of prior to letting it sit. ;)

The gas is going to be crap after 6 years as well. Do a tune up take it easy (no wot and cycle through the old gas) and then put it on scan tool.
