I need the timing settings for a 1987 transit ice cream van with a diesel engine with the cav pump

Hi, You need to connect a hand priming pump between the fuel supply pipe & the fuel filter keep squeezing the pump until it becomes firm. continue squeezing the priming bulb durin engine cranking.

it might be a relay located in the engine compartment instead of a fuse

Diesel !
cam ? timing? or the injector pump... ??????
ask Isuzu for a book.
wiki says, what is a space cab.>?? a 4,000 lb truck./van, sure.

The 4BE1 is a 3.6L direct injection engine. It replaced the 4BC2 in Isuzu NPR's from 1987- non turbo, VE rotary injection pump or Zexel/Diesel Kiki A-type injection pump. Bore and stroke are both 105mm. Power ratings in the last versions (NKR300)are 74 kW (100 SAE HP) at 3,500rpm and 242 Nm at 2000rpm.

depends if it has one or two belts ie like transit uses one for the engine escort diesel has seperate belt dont do it wrong can be very expensive it must all be set right crank at t.d.c cam needs lining and the pump

YOU COULD HAVE RESTRICTED FUEL FILTER OR FUEL PUMP COULD BE FAILING. FUEL PRESSURE SHOULD BE 9 - 13 PSI FOR THE GAS ENGINE.IF YOU HAVE 6.2 DIESEL ENGINE YOU FUEL FILTER STOPPED UP OR YOU HAVE FAULTY LOW PRESSURE TRANSFER PUMP.YOU COULD HAVE FAULTY FUEL SOLENOID AT THE INJECTION PUMP.

Take in to someone that is reputable with diesel engines-injectors and /or their timing is critical on these engines....

there might be water in the fuel pump trying openning sedometer and pump out the water until diesel comes

hi, is this tapping loud, they are normally clattery, especialy if fitted with a lucas or cav fuel pump.
an injector has lots of smoke and thumps in most cases.
get back to me

i am curious... what year is this van... and what diesel engine does it have. i am a professional diesel mechanic that specializes on ford engines and i never herd of an R2 engine. it has got to be a 6.2l, 7.3l or 6.0l engine... at any rate none of these engines have a timing belt... unless you have some kind of import model that i am not familiar with. if that is the case them i will try to find out all the info i can.
