Fuel injection colour codes.
Discussion
Not sure if I have 2 injection wires the wrong way around, although I did number them before I took them off, presuming they were in the right position before. Now I notice each injector has different colour codes and colour stripes. Can anyone point me in the direction of the correct colour code for each injector, this being a 1995 series 1.
Thanks,
Hugo.
By the way, Car now on the road, taxed, new reg number, etc.

Looking at mine, each injector head has 2 wires, but they are all different, like, white and green, with a smaller coloured stripe, etc,
Using the various colour combinations, is the same as numbering them, but numbers would have been easier.......
Will phone Viper people in the USA tomorrow, as I have to order a new rear view mirror - mine was missing.

I guess you mean that the plugs for two injectors are swapped over. This would only matter if you have sequential injection. I don't know whether the Viper does, but it is not at all common on standard production cars so I think it's unlikely. If you could find out for sure, you could set your mind at rest. One quick and easy way to find out is to connect NOID lamps to the two injectors in question. Most likely the lamps would flash in phase, telling you it doesn't matter which way round you connect them.
Vipers are sequential...........so it does matter, alot.
And if the body shape wasn't wind-cheating in the modern idiom, at least the Viper had the raw horsepower to hustle the potato sack along at satisfyingly high speeds (a claimed 165 miles per hour.) The unique V-10 was what one might expect to get when crossing an American truck engine with an Italian block fabricator. The huge 488 cubic inch displacement is a hint of its American heritage as is the two-valves-per-cylinder overhead valve configuration. The continental influences include the aluminum block and head construction and the sequential multipoint fuel injection system. In its first iteration this engine tossed out 400 horsepower at a lazy 4600 rpm and a colossal 465 pound-feet of torque at a mere 3600 rpm. Bolted into the 3600 pound Viper, it resulted in zero-to-60 mph sprints of 4.6 seconds or so.

if you are unsure if they are firing or not then its quite easy to tell with a makeshift automotive stethoscope, AKA a bit of tube.
All you need is about a metre of 1/4" tubing and shove one end in your ear (obviously no further than your elbow) and then put the other end on the back of the injector, if its working there will be a distinctive and quite loud clicking noise, you will likely be able to hear the others also faintly in the background but so long as one is working you can get a base line from that one for what you are listening for on the others.
Not sure about Gen 1 but gen 2 will set a code if they are open circuit and the ECU will shut them down in if it thinks there is a fault elsewhere in the ignition system.
If the injector plugs have been off and not put back carefully then it is possible the connectors in the plug have been pushed back so they aren’t making contact as the plugs are a bit crappy, but you can disassemble them and put them back together with the pins in the correct alignment and then plug them back into the injector carefully.
