There are 2 wires per injecter if they both came out of the same plug and you are sure that you have the one wire in the right side the red goes to the other side of the plug.
IF THIS does not make sence to you PLEASE TRY and GIVE MORE DETAIL.

Why is my truck acting like its running out of gas once it is at constant speed?

Maybe your fuel injecter is plugging up with dirt, or one of the injecters are going bad

91 s10 surges and wants to die when clutch is disengaged

Sounds to me to be more of an ignition coil problem. Remove a plug and replace the wire to the top of it. Rest the firing tip against your exhaust manifold and have someone else crank the motor. The spark should be blue or white. If it is orange or red you have a bad coil.

What is the correct procedure to check and correct the distributor timing.

The distributor is driven directly by the camshaft. The end of the camshaft contains a set of grooves that engage the distributor shaft. These grooves prevent the distributor from being incorrectly installed.


  1. Using masking tape, remove the spark plug wires from the cap and number them for installation as they are removed.
From 1988-onwards, all Honda Civic series models were fuel injected.
  1. Disconnect the vacuum hoses, the primary wire and the high tension wire. If equipped with fuel injection, remove the four prong connector from the crank angle sensor.
  2. Remove the hold-down bolt(s) and pull the distributor from the head.

On CRX with fuel injection, there are three bolts.
  1. Crank the engine until No. 1 piston is at TDC of its compression stroke.
  2. Using a new O-ring, install it on the distributor housing.
  3. On the all models, the distributor drive gear remains engaged when the distributor is removed. To install, align the distributor and turn the shaft until the drive locks and the distributor seats in the cylinder head.
  4. Loosely install the hold-down bolt(s). Tighten the bolt(s) temporarily and replace the cap.
  5. Connect all wires and hoses.
  6. Start the engine and adjust the ignition timing.

Fig. : Remove the distributor vacuum hoses, being careful not to get them confused. If necessary, label the hoses as performed in spark plug wire removal

Fig. : Unplugging the four-prong connector from the crank angle sensor. Notice the secure snap-connection and water-resistant O-ring seal around the inner circumference

Hope helped with this (remember rated this help) Good luck.

My s10 will turn over, but wont squirt gas through injecter

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's
