Question about 1998 Jeep Wrangler
I HAVE A 4.0 LITER WITH THE EFI SYSTEM ON IT AND THE PROBLEM IS ON A COLD START IT JUST WANTS TO CRANK AND CRANK LIKE ITS NOT GETTING GAS. HOWEVER IF I CRANK IT FOR A FEW SECONDS AND THEN BACK OF AND CRANK IT AGAIN IT WILL USUALLY START RIGHT AWAY. MY QUESTION IS DOES THIS SYSTEM NEED TO BE PRESSURIZED AND IF SO HOW DO I DO IT?
FUEL PUMP WILL PUT PRESSURE IN FUEL RAIL FOR YOU. sounds like fuel pressure in the fuel rail is losing pressure usally caused from fuel pump starting to go out. check pressure with fuel gauge. screw it onto the fuel rail connection turn the key forward (do not start ) then turn key off presure should hold around 16 psi. if the gauge starts to drift back down then the fuel pump is going to go out ( sometime)
