adjusting crossfire fuel injection on a 83 camaro z28 305?
87582
Been down this road with an 82 Transam that had crossfire injection.\n\nMy recommendation for you is to replace the intake manifold and install a holley 4 barrel.\n\nIn the end you'll save alot of time and effort.

You need 4 spark plugs. They are located under the cover on the top of the engine. Remove the 4 bolts (13mm) on the cover and carefully unplug the harness on the end of the cover to your right. Pull the cover straight up (you will have some resistance). Before removing the plugs blow out any dirt and debris so that it can not fall into the engine with the plugs removed. Then remove the plugs, I remove and replace one plug at a time. After all 4 plugs have been replaced carefully put the cover back in place making sure the plug wires are in position. Install the 4 bolts and plug in the wire harness.\nNOTE: You may want to replace the spark plug wires while you have it unassembled. About $20.00 at a parts store.\nAlso, do not over tighten the plugs or the bolts on the cover.\nAbout a 20 minute job. if that.

Repeal, or Alter the Clinton/Gore EPA-OBD II Law. This Law Mandates that all Gasoline Powered Vehicles in the USA from 1996 to the Present must Run at 14.7 Parts of Air to 1 Part of Fuel. Any Deviation from that , and the Vehicle will Fail Inspection. Even if Emissions are Lowered, and Fuel Economy is Improved, Failure! And the Vehicle will be Illegal to Operate! I've found a way to Convert Regular Pump Gasoline into Propane. 100 Parts of Air, to 1 Part of Fuel. 50 + MPG, with even the Largest SUV! See, all Petroleum is the same, on a Molecular Level. Only the Dispersal is Altered. I'm not the First, only the Latest. I've been to the US Patent Office to Check Out the "Myth" about Vapor Fuel Units that have been Bought Out, and kept off the Market. Guess What? It's for Real! Case in Point, the Pogue Carburetor. It is Patented with a Claim of 100 MPG, with a Flathead Ford Engine Powered Vehicle, that with a Conventional Fuel System got 15 MPG!And this was before WW II ! So, there's really no Point in even trying to Patent a Vapor Fuel System. It's always Stopped Cold! And Now, with the Clinton/Gore EPA-OBD II Law, it's Pointless to even Try! Watch the Process, the Next Time Your Car is Inspected!" Big Brother" has Won! Now, if I am Wrong, then how is it that Engines DO Run on Bottled Propane? That Requires a Large, Expensive, Cumbersome Tank, Expensive Tank to Engine Metering Equipment, and the Added Hassle of Specialized Refueling! Even with Gas at $3.00 per Gallon, it's just not worth It! My System is Safe, Compact, and uses Low Pressure Air to Do It's Thing. It all Fits very Neatly under the Hood. But again, it's Illegal because the Vehicle must Conform to Original Gov't Mandated Spec's, 14.7 to 1 ! I can understand why a Vehicle should be Required to Pass an Inspection to Limit Excessive Emissions. But, to "Outlaw" a Vehicle for not Emitting Enough Pollution? This is Insane! My Environmental Project Proposal for Today would be to Change this Insane Law!

With a wrench the same way as with a car.  It's called fine tuning.

www.3si.org/forum\n\na wealth of information, anything and everything can be found here if it relates to 3000gt and Stealths.\n\nyour options are endless, most people begin with intake, exhaust and boost.  a K&N filter, gutted converters, and boost control ($10 bleeder valve to $300 AVCR) can get a Stealth into low 13's or high 12's.    second mods could be\ninjectors and fuel control, clutch, and bigger turbo's.  \n\nc'ya around

You might want to check the injectors themselves they will go bad, however if you had a simultaneous failure of all three then look at any wiring or the fuel rail to see if there's any apparent damage.

If it doesn't bolt up your 5 liter engine is probably a Buick, Olds or Pontiac 307 not a 305.\n  These engines have a wider block. The intake manifold is a couple inches wider than the Chevrolet version.\n   GM installed these engines in some Chevys. They also put the Chevy engines in B.O.P cars.

fuel pumps do turn and turn on as they are powered by motors.\nIf it works when you apply raw power, then the problem is in the control circuit. It could be the ignition or somewhere else. You did check the fuses? there is often two fuseboxes and occasionally external fuse links. It could also be a bad relay.\n\nYou will need a wiring diagram. The law has recently changed so that you can purchase the actual factory diagram somewhere, poke around.\nhttp://ahdol.com/\n\nI have usually, as in more often than not, found Haynes and Chilton's manual wiring to be incomplete, or worse, misinformed

get a second opinion- Sorry a fuse is good or bad - no middle. you have an issue withe the sending unit in the tank - it is a simple but not a cheap part- most of the sending units have an arm that rides up and down with the fuel level- sometimes where the arm rubs against can loose contact and cause a gauge to read empty- or loose ground withe the tank. should be cheaper than 500.00 maybe

a solid lift cam from a 1969 302 z28 engine, 202 intake valves, [preferably double hump heads, if you cant find these use 882 casting truck heads and have them cut for 2.02 intake valves.] a 700 double pumper holley, and most importantly,TIMING!!!! I MEAN BOTH IGNITION AND CAM TIMING. BUY A DOUBLE ROLLER TIMING SET AND RUN IT ON THE ADVANCED MARK. THEN BUY A RECURVE KIT FOR YOUR DISTRIBUTOR, RUN THE VACUUM LINE TO THE PORT ON THE CARB THAT SUCKS VACUUM ON ACCELERATION. WHEN YOU SET YOUR TIMING, REV THE ENGINE UP TO 3000 RPM AND HOLD IT THERE. ADVANCE THE TIMING UNTIL THE ENGINE BEGINS TO MISS OUT, THEN BACK THE TIMING OFF UNTIL IT RUNS SMOOTHLY AGAIN, AND TIGHTEN IT UP, THEN RE-HOOK YOUR VACUUM LINE TO THE CARB. DOING THIS WILL ENSURE YOU THAT THE CAM TIMING AND IGNITION TIMING ARE ON THE SAME AXIS, A MUST FOR STREET CAR PERFORMANCE, YOU WILL HAVE TO RUN PREMIUM FUEL, I RECOMMEND AMACO ULTIMATE, GOOD LUCK.

There have been different systems in the past 30yrs. For a general concept check out the link below.\n\nDepending on what you are looking for: EFI electronic fuel injection, TBI throttle body injection, CBI central body injection, CPI central port injection or SCPI sequential central port injection or MFI multi-port fuel injection (which is most popular nowadays) you can get an idea of what it is at this link.\nFor a specific version based on the vehicle you own, try a Hanes service manual.

Use silicone,just make sure it is clean and dry,and then wait at least twenty four hours before putting gasoline in the tank.It worked for me,except it wasn't a Nissan Maxima.

there is a company out there called "Tanks, inc." they should be on line. they have a lot of different fuel tanks that they make and i am sure they can help you. gramps

Where are you getting your fuel pumps from?... I have a friend who is a mechanic and he said most auto parts stores sell junk fuel pumps (for GM atleast)....You'll put 10 in before you actually get a good one....\n\nNow if you want to spend a couple extra bucks, go to the GM dealer and buy one from them.... Thats what I did with my truck and it wasen't that much more...\n\nOr ask your auto parts stores, if they sell AC Delco pumps...\n\nGood Luck
