I will pick it up tomorrow and replace it myself.
If this doesn't solve the problem, I believe I should be looking at replacing the Fuel pump!!!Right?
Thanx.

Most likely, its the crank position sensor. If you suspect a fuel pump later, perform a fuel pressure test. Carefully remove the plastic cover on the engine,
and you'll find a nipple on the fuel injector rail at the right front of the engine.
( looking at the firewall from the front of the vehicle, the nipple will be to your left hand side.) Connect a fuel pressure gauge - 3.5-3.8 bar pressure is the norm.
By the way, if you have an ohm meter and a way to heat the old crank sensor, you can prove that its bad. Hook up the ohm meter to the sensor, max. resistance should be 1400 ohms. Then slowly heat the sensor ( I use a heat gun ) and as the sensor gets hot, if its bad, it will go way over 1400 ohms, or the meter may even read "O L" (or, open.)
(Of course, you try this at your own risk, no responsibility assumed by me in any way whatsoever.)
